Marijuana

These aren't your filthy hippies and stoners looking for an excuse to toke (not that there's anything wrong with that!): The American Legion is calling for the federal government to reclassify marijuana to acknowledge its potential benefits as a medical treatment.

As Jacob Sullum previously noted, The Drug Enforcement Agency (DEA) is stubbornly refusing to change the federal classification of marijuana as a drug that has no "accepted medical use" until science proves them wrong. Fortunately they're easing off on the Catch-22 situation that has resulted in this classification making it extremely difficult for researchers to perform the very scientific testing that could determine marijuana's medical value.

One of the potential medical values of medical marijuana is as a treatment for Post-Traumatic Stress Disorder (PTSD). And in what must certainly at this point make it abundantly clear where the majority of Americans stand on marijuana use, the American Legion has just voted at its national convention to support a resolution calling on Congress to legislatively reclassify cannabis and place it in a category that recognizes its potential value.

The resolution, readable here at marijuana.com, highlights a number of important statistics that have helped push the Legion to support it. Across two years, the Department of Veterans Affairs have diagnosed thousands of Afghanistan and Iraq War veterans as having PTSD or Traumatic Brain Injuries (TBI). More than 1,300 veterans in fiscal year 2009 were hospitalized for brain injuries. And the resolution notes that systems in the brain can respond to 60 different chemicals found in cannabis.

Therefore, the American Legion wants the DEA to license privately-funded medical marijuana and research facilities and to reclassify marijuana away from being lumped in with drugs like cocaine and meth.

Tom Angell over at marijuana.com notes that Sue Sisley, a psychiatrist and medical marijuana researcher, has been lobbying the Legion and their local posts to get their support. Sisley is notable for actually getting federal permission to research marijuana as a treatment for PTSD and then getting dumped by the University of Arizona (where she worked) in 2014.

What does this mean for a legislative effort to give VA docs permission to actually talk about medical marijuana as a treatment for veterans? As I noted in May, there was an amendment to a military appropriations bill that would end a gag order that prohibits VA doctors from recommending or even discussing medical marijuana treatment with patients, even in states where it had been legalized. The amendment would end the gag order, but wouldn't permit the VA to prescribe or pay for marijuana.

The amendment passed the House and Senate, but as Angell notes, after the two sides went through the reconciliation to hammer out any difference, the language completely disappeared. It is no longer part of the Veterans Administration package.

Legislators return to session today to hammer out last-minute spending bills to keep the government running (and the Democrats and Republicans are currently in disagreement on how long to extend spending authorizations for the incoming administration). Technically the amendment's language could be restored. (1 image)

DEA, 81 FR 53779-53781, August 12, 2016

Status of Research Into the Medical Uses for Marijuana

State-level public initiatives, including laws and referenda in support of the medical use of marijuana, have generated interest in the medical community and the need for high quality clinical investigation as well as comprehensive safety and effectiveness data. In order to address the need for high quality clinical investigations, the state of California established the Center for Medicinal Cannabis Research (CMCR, www.cmcr.ucsd.edu) in 2000 ''in response to scientific evidence for therapeutic possibilities of cannabis[9] and local legislative initiatives in favor of compassionate use'' (Grant, 2005). State legislation establishing the CMCR called for high quality medical research that would ''enhance understanding of the efficacy and adverse effects of marijuana as a pharmacological agent,'' but stressed the project ''should not be construed as encouraging or sanctioning the social or recreational use of marijuana.'' The CMCR funded many of the published studies on marijuana's potential use for treating multiple sclerosis, neuropathic pain, appetite suppression and cachexia. However, aside from the data produced by CMCR, no state-level medical marijuana laws have produced scientific data on marijuana's safety and effectiveness.

FDA approves medical use of a drug following a submission and review of an NDA or BLA. The FDA has not approved any drug product containing marijuana for marketing. Even so, results of small clinical exploratory studies have been published in the current medical literature. Many studies describe human research with marijuana in the United States under FDA-regulated IND applications.

However, FDA approval of an NDA is not the only means through which a drug can have a currently accepted medical use in treatment in the United States. In general, a drug may have a ''currently accepted medical use'' in treatment in the United States if the drug meets a five-part test. Established case law (Alliance for Cannabis Therapeutics v. DEA, 15 F.3d 1131, 1135 (D.C. Cir. 1994)) upheld the Administrator of DEA's application of the five-part test to determine whether a drug has a ''currently accepted medical use.'' The following describes the five elements that characterize ''currently accepted medical use'' for a drug[10]:

i. the drug's chemistry must be known and reproducible

''The substance's chemistry must be scientifically established to permit it to be reproduced into dosages which can be standardized. The listing of the substance in a current edition of one of the official compendia, as defined by section 201 G) of the Food, Drug and Cosmetic Act, 21 U.S.C. 321G), is sufficient to meet this requirement.''

ii. there must be adequate safety studies

''There must be adequate pharmacological and toxicological studies, done by all methods reasonably applicable, on the basis of which it could fairly and responsibly be concluded, by experts qualified by scientific training and experience to evaluate the safety and effectiveness of drugs, that the substance is safe for treating a specific, recognized disorder.''

iii. there must be adequate and well- controlled studies proving efficacy

''There must be adequate, well- controlled, well-designed, well-conducted, and well-documented studies, including clinical investigations, by experts qualified by scientific training and experience to evaluate the safety and effectiveness of drugs, on the basis of which it could be fairly and responsibly concluded by such experts that the substance will have the intended effect in treating a specific, recognized disorder.''

iv. the drug must be accepted by qualified experts

''The drug has a New Drug Application (NDA) approved by the Food and Drug Administration, pursuant to the Food, Drug and Cosmetic Act, 21 U.S.C. 355. Or, a consensus of the national community of experts, qualified by scientific training and experience to evaluate the safety and effectiveness of drugs, accepts the safety and effectiveness of the substance for use in treating a specific, recognized disorder. A material conflict of opinion among experts precludes a finding of consensus.'' and

v. the scientific evidence must be widely available

''In the absence of NDA approval, information concerning the chemistry, pharmacology, toxicology, and effectiveness of the substance must be reported, published, or otherwise widely available, in sufficient detail to permit experts, qualified by scientific training and experience to evaluate the safety and effectiveness of drugs, to fairly and responsibly conclude the substance is safe and effective for use in treating a specific, recognized disorder.''

Marijuana does not meet any of the five elements necessary for a drug to have a ''currently accepted medical use.''

Firstly, the chemistry of marijuana, as defined in the petition, is not reproducible in terms of creating a standardized dose. The petition defines marijuana as including all Cannabis cultivated strains. Different marijuana samples derived from various cultivated strains may have very different chemical constituents including delta9-THC and other cannabinoids (Appendino et al., 2011). As a consequence, marijuana products from different strains will have different safety, biological, pharmacological, and toxicological profiles. Thus, when considering all Cannabis strains together, because of the varying chemical constituents, reproducing consistent standardized doses is not possible. Additionally, smoking marijuana currently has not been shown to allow delivery of consistent and reproducible doses. However, if a specific Cannabis strain is grown and processed under strictly controlled conditions, the plant chemistry may be kept consistent enough to produce reproducible and standardized doses.

As to the second and third criteria; there are neither adequate safety studies nor adequate and well-controlled studies proving marijuana's efficacy. To support the petitioners' assertion that marijuana has accepted medical use, the petitioners cite the American Medical Association's (AMA) 2009 report entitled ''Use of Cannabis for Medicinal Purposes.'' The petitioners claim the AMA report is evidence the AMA accepts marijuana's safety and efficacy. However, the 2009 AMA report clarifies that the report ''should not be viewed as an endorsement of state-based medical cannabis programs, the legalization of marijuana, or that scientific evidence on the therapeutic use of cannabis meets the same and current standards for a prescription drug product.[11]''

Currently, no published studies conducted with marijuana meet the criteria of an adequate and well-controlled efficacy study. The criteria for an adequate and well-controlled study for purposes of determining the safety and efficacy of a human drug are defined under the Code of Federal Regulations (CFR) in 21 CFR 314.126. In order to assess this element, FDA conducted a review of clinical studies published and available in the public domain before February, 2013. Studies were identified through a search of PubMed[12] for articles published from inception to February 2013, for randomized controlled trials using marijuana to assess marijuana's efficacy in any therapeutic indication. Additionally, the review included studies identified through a search of bibliographic references in relevant systematic reviews and identified studies presenting original research in any language. Selected studies needed to be placebo-controlled and double-blinded. Additionally, studies needed to encompass administered marijuana plant material. There was no requirement for any specific route of administration, nor any age limits on study subjects. Studies were excluded that used placebo marijuana supplemented by the addition of specific amounts of THC or other cannabinoids. Additionally, studies administering marijuana plant extracts were excluded.

The PubMed search yielded a total of 566 abstracts of scientific articles. Of these abstracts, a full-text review was conducted with 85 papers to assess eligibility. Of the studies identified through the search of the references and the 566 abstracts from the PubMed search, only 11 studies met all the criteria for selection (Abrams et al., 2007; Corey-Bloom et al., 2012; Crawford and Merritt, 1979; Ellis et al., 2009; Haney et al., 2005; Haney et al., 2007; Merritt et al., 1980; Tashkin et al., 1974; Ware et al., 2010; Wilsey et al., 2008; Wilsey et al., 2013). These 11 studies were published between 1974 and 2013. Ten of these studies were conducted in the United States and one study was conducted in Canada. The identified studies examine the effects of smoked and vaporized marijuana for the indications of chronic neuropathic pain, spasticity related to Multiple Sclerosis (MS), appetite stimulation in human immunodeficiency virus (HIV) patients, glaucoma, and asthma. All studies used adult subjects.

The 11 identified studies were individually evaluated to determine if they successfully meet accepted scientific standards. Specifically, they were evaluated on study design including subject selection criteria, sample size, blinding techniques, dosing paradigms, outcome measures, and the statistical analysis of the results. The analysis relied on published studies, thus information available about protocols, procedures, and results were limited to documents published and widely available in the public domain. The review found that all 11 studies that examined effects of inhaled marijuana do not currently prove efficacy of marijuana in any therapeutic indication based on a number of limitations in their study design; however, they may be considered proof of concept studies. Proof of concept studies provide preliminary evidence on a proposed hypothesis involving a drug's effect. For drugs under development, the effect often relates to a short-term clinical outcome being investigated. Proof of concept studies often serve as the link between preclinical studies and dose ranging clinical studies. Thus, proof of concept studies generally are not sufficient to prove efficacy of a drug because they provide only preliminary information about the effects of a drug.

In addition to the lack of published adequate and well-controlled efficacy studies proving efficacy, the criteria for adequate safety studies has also not been met. Importantly, in its discussion of the five-part test used to determine whether a drug has a ''currently accepted medical use,'' DEA said, ''No drug can be considered safe in the abstract. Safety has meaning only when judged against the intended use of the drug, its known effectiveness, its known and potential risks, the severity of the illness to be treated, and the availability of alternative remedies'' (57 FR 10504). When determining whether a drug product is safe and effective for any indication, FDA performs an extensive risk-benefit analysis to determine whether the risks posed by the drug product's side effects are outweighed by the drug product's potential benefits for a particular indication. Thus, contrary to the petitioner's assertion that marijuana has accepted safety, in the absence of an accepted therapeutic indication which can be weighed against marijuana's risks, marijuana does not satisfy the element for having adequate safety studies such that experts may conclude that it is safe for treating a specific, recognized disorder.

The fourth of the five elements for determining ''currently accepted medical use'' requires that the national community of experts, qualified by scientific training and experience to evaluate the safety and effectiveness of drugs, accepts the safety and effectiveness of the substance for use in treating a specific, recognized disorder. A material conflict of opinion among experts precludes a finding of consensus. Medical practitioners who are not experts in evaluating drugs are not qualified to determine whether a drug is generally recognized as safe and effective or meets NDA requirements (57 FR 10499-10505).

There is no evidence that there is a consensus among qualified experts that marijuana is safe and effective for use in treating a specific, recognized disorder. As discussed above, there are not adequate scientific studies that show marijuana is safe and effective in treating a specific, recognized disorder. In addition, there is no evidence that a consensus of qualified experts have accepted the safety and effectiveness of marijuana for use in treating a specific, recognized disorder. Although medical practitioners are not qualified by scientific training and experience to evaluate the safety and effectiveness of drugs, we also note that the AMA's report, entitled ''Use of Cannabis for Medicinal Purposes,'' does not accept that marijuana currently has accepted medical use. Furthermore, based on the above definition of a ''qualified expert'', who is an individual qualified by scientific training and experience to evaluate the safety and effectiveness of a drug, state-level medical marijuana laws do not provide evidence of a consensus among qualified experts that marijuana is safe and effective for use in treating a specific, recognized disorder.

As to the fifth part of the test, which requires that information concerning the chemistry, pharmacology, toxicology, and effectiveness of marijuana to be reported in sufficient detail, the scientific evidence regarding all of these aspects is not available in sufficient detail to allow adequate scientific scrutiny. Specifically, the scientific evidence regarding marijuana's chemistry in terms of a specific Cannabis strain that could produce standardized and reproducible doses is not currently available.

Alternately, a drug can be considered to have a ''currently accepted medical use with severe restrictions'' (21 U.S.C. 812(b)(2)(B)), as allowed under the stipulations for a Schedule II drug. Yet, as stated above, currently marijuana does not have any accepted medical use, even under conditions where its use is severely restricted.

In conclusion, to date, research on marijuana's medical use has not progressed to the point where marijuana is considered to have a ''currently accepted medical use'' or a ''currently accepted medical use with severe restrictions.''

The DEA has an abnormal desire to stop pot use IMHO.

Nothing the government has stated about pot is true which in my opinion makes people question what government says about other drugs. This leads to people trying and getting hooked on other more truly dangerous drugs like meth, crack, heron and more. Some of the most dangerous drugs are man-made drugs which leave people mentally broken for life such as K2/spice.

JFYI
I had smoked pot for nearly 5 years back in the 80's. Stopped without an issue and never had any side affects. It did not drive you crazy it just mellowed you out. It did not make me steal, rape or assault people.

Facts?

A friend who is a Vietnam vet, also retired from the California National Guard about 4 years ago.

He has PTSD and has been on prescription psych drugs for about 30 years or more. He called me up a couple of years ago, all jazzed because his VA psychiatrist took him off of all prescription drugs. For the first time in decades he's off of the hated psych meds and drug free, but with California Medical Marijuana as a back up, as needed. He's officially considered cured, and weed helped.

That one story is enough to convince me that MM should be available to all.

Marijuana Use and PTSD among Veterans

Marcel O. Bonn-Miller, Ph.D. and Glenna S. Rousseau, Ph.D.

Marijuana use for medical conditions is an issue of growing concern. Some Veterans use marijuana to relieve symptoms of PTSD and several states specifically approve the use of medical marijuana for PTSD. However, controlled studies have not been conducted to evaluate the safety or effectiveness of medical marijuana for PTSD. Thus, there is no evidence at this time that marijuana is an effective treatment for PTSD. In fact, research suggests that marijuana can be harmful to individuals with PTSD.

Epidemiology

Marijuana use has increased over the past decade. In 2013, a study found that 19.8 million people reported using marijuana in the past month, with 8.1 million using almost every day (1). Daily use has increased 60% in the prior decade (1). A number of factors are associated with increased risk of marijuana use, including diagnosis of PTSD (2), social anxiety disorder (3), other substance use, particularly during youth (4), and peer substance use (5).

Cannabis Use Disorder among Veterans Using VA Health Care

There has been no study of marijuana use in the overall Veteran population. What we do know comes from looking at data of Veterans using VA health care, who may not be representative of Veterans overall. When considering the subset of Veterans seen in VA health care with co-occurring PTSD and substance use disorders (SUD), cannabis use disorder has been the most diagnosed SUD since 2009. The percentage of Veterans in VA with PTSD and SUD who were diagnosed with cannabis use disorder increased from 13.0% in fiscal year (FY) 2002 to 22.7% in FY 2014. As of FY 2014, there are more than 40,000 Veterans with PTSD and SUD seen in VA diagnosed with cannabis use disorder (6).

<p>
<b>Cannabis use disorder is the most diagnosed SUD among Veterans with PTSD in 
VA health care in FY14. Rates of cannabis use disorder diagnoses grew from 13.0% 
in FY02 to 22.7% in FY14</b>. Cocaine use disorder was the most diagnosed SUD 
among Veterans with PTSD in FY02, at 18.9%. In FY09, cocaine became less common 
than cannabis use disorder (15.4% and 15.9% respectively), and as of FY14, 
cocaine use disorder is the second most common SUD diagnosis among Veterans with 
PTSD, at 14.8%. Among this subset of Veterans, opioid use disorder was diagnosed 
at a rate of 9.9% in FY02, rising to 12.5% in FY14. Amphetamine use disorder was 
diagnosed at a rate of 2.6% in FY02 and rose to 4.4% in FY14.

Problems Associated with Marijuana Use

Marijuana use is associated with medical and psychiatric problems. These problems may be caused by using, but they also may reflect the characteristics of the people who use marijuana. Medical problems include chronic bronchitis, abnormal brain development among early adolescent initiators, and impairment in short-term memory, motor coordination and the ability to perform complex psychomotor tasks such as driving. Psychiatric problems include psychosis and impairment in cognitive ability. Quality of life can also be affected through poor life satisfaction, decreased educational attainment, and increased sexual risk-taking behavior (7). Chronic marijuana use also can lead to addiction, with an established and clinically significant withdrawal syndrome (8).

Active Ingredients and Route of Administration

Marijuana contains a variety of components (cannabinoids), most notably delta-9-tetrahydrocannabinol (THC) the primary psychoactive compound in the marijuana plant. There are a number of other cannabinoids, such as cannabidiol (CBD), cannabinol (CBN), and cannabigerol (CBG). Marijuana can vary in cannabinoid concentration, such as in the ratio of THC to other cannabinoids (CBD in particular). Therefore, the effects of marijuana use (e.g., experience of a high, anxiety, sleep) vary as a function of the concentration of cannabinoids (e.g., THC/CBD). In addition, the potency of cannabinoids can vary. For example, the concentration of THC in the marijuana plant can range in strength from less than 1% to 30% based upon strain and cultivation methods. In general, the potency of THC in the marijuana plant has increased as much as 10- fold over the past 40 years (9,10). Recently, cannabis extract products, such as waxes and oils, have been produced and sold in which the concentration of THC can be as high as 90%. Thus, an individual could unknowingly consume a very high dose of THC in one administration, which increases the risk of an adverse reaction.

Marijuana can be consumed in many different forms (e.g., flower, hash, oil, wax, food products, tinctures). Administration of these forms also can take different routes: inhalation (smoking or vaporizing), ingestion, and topical application. Given the same concentration/ratio of marijuana, smoking or vaporizing marijuana produces similar effects (11); however, ingesting the same dose results in a delayed onset and longer duration of effect (12). Not all marijuana users may be aware of the delayed effect caused by ingestion, which may result in greater consumption and a stronger effect than intended.

Neurobiology

Research has consistently demonstrated that the human endocannabinoid system plays a significant role in PTSD. People with PTSD have greater availability of cannabinoid type 1 (CB1) receptors as compared to trauma-exposed or healthy controls (13,14). As a result, marijuana use by individuals with PTSD may result in short-term reduction of PTSD symptoms. However, data suggest that continued use of marijuana among individuals with PTSD may lead to a number of negative consequences, including marijuana tolerance (via reductions in CB1 receptor density and/or efficiency) and addiction (15). Though recent work has shown that CB1 receptors may return after periods of marijuana abstinence (16), individuals with PTSD may have particular difficulty quitting (17).

Marijuana as a Treatment for PTSD

The belief that marijuana can be used to treat PTSD is limited to anecdotal reports from individuals with PTSD who say that the drug helps with their symptoms. There have been no randomized controlled trials, a necessary "gold standard" for determining efficacy. Administration of oral CBD has been shown to decrease anxiety in those with and without clinical anxiety (18). This work has led to the development and testing of CBD treatments for individuals with social anxiety (19), but not yet among individuals with PTSD. With respect to THC, one open trial of 10 participants with PTSD showed THC was safe and well tolerated and resulted in decreases in hyperarousal symptoms (20).

Treatment for Marijuana Addiction

People with PTSD have particular difficulty stopping their use of marijuana and responding to treatment for marijuana addiction. They have greater craving and withdrawal than those without PTSD (21), and greater likelihood of marijuana use during the six months following a quit attempt (17). However, these individuals can benefit from the many evidence-based treatments for marijuana addiction, including cognitive behavioral therapy, motivational enhancement, and contingency management (22). Thus, providers should still utilize these options to support reduction/abstinence.

Clinical Recommendations

Treatment providers should not ignore marijuana use in their PTSD patients. The VA/DoD PTSD Clinical Practice Guideline (2010) recommends providing evidence-based treatments for the individual disorders concurrently. PTSD providers should offer education about problems associated with long-term marijuana use and make a referral to a substance use disorder (SUD) specialist if they do not feel they have expertise in treating substance use.

Individuals with comorbid PTSD and SUD do not need to wait for a period of abstinence before addressing their PTSD. A growing number of studies demonstrate that that these patients can tolerate trauma-focused treatment and that these treatments do not worsen substance use outcomes. Therefore, providers have a range of options to help improve the lives of patients with the co-occurring disorders. For more information, see PTSD and Substance Use Disorders in Veterans.
