Medical Marihuana

NYSACOP Medical Marihuana Statement

We hope that New York’s medical marijuana program is not just a first step towards more general distribution and certainly hope that it is not a step towards legalization. Our concerns have always been around the impact of increased marijuana use on highway safety and the health problems spelled out by the American Medical Association and the American Psychiatric Association caused by chronic use especially among adolescents. Going forward, we hope the professional medical community leads the program in the state and not elected officials. From our own experience in researching the issue it is possible that a limited class of patients may benefit from the medicinal properties of marijuana. If New York’s program is genuinely limited to 20 hospitals and the limited list of diseases and conditions already mentioned, then New York’s program could be a model for the rest of the country to follow.  We encourage everyone to follow the program closely and read the most recent statements issued by the AMA and the APA steadfastly opposed to the legalization of marijuana.

BREAKING: AMA OPPOSES LEGALIZATION & EARLY WA DATA SHOWS INCREASE IN MARIJUANA-POSITIVE DRIVERS

SAM LOGO

AMERICAN MEDICAL ASSOCIATION OPPOSES MARIJUANA LEGALIZATION; SUPPORTS HEALTH-FIRST APPROACH TO MARIJUANA USE

Largest medical group in the US explicitly rejects calls to become "neutral" on legalization; supports full funding of the Office of National Drug Control Policy; calls for proper study of Colorado and Washington policies. It joins the American Psychiatric Association, who issued a statement last week outlining the public health harms of marijuana.

NATIONAL HARBOR, MD-The delegates at the 2013 Interim Meeting of the American Medical Association (AMA) House of Delegates, in National Harbor, Maryland, today voted to pass a resolution on marijuana, "Council of Science & Public Health Report 2 in Reference Committee K," explicitly opposing marijuana legalization - fending off a challenge to "neutralize" their position. The report changes H-95.998 AMA Policy Statement on Cannabis to read in part that: "Our AMA believes that (1) cannabis is a dangerous drug and as such is a public health concern; (2) sale and possession of cannabis should not be legalized."

"The AMA today reiterated the widely held scientific view that marijuana is dangerous and should not be legalized," commented Dr. Stuart Gitlow, Chair-Elect of the AMA Council on Science and Health and SAM Board Member. "We can only hope that the public will listen to science - not 'Big Marijuana' interests who stand to gain millions of dollars from increased addiction rates."

Additionally, the report called for several provisions consistent with Project SAM's marijuana pillars, including efforts to "discourage cannabis use, especially by persons vulnerable to the drug's effects and in high-risk situations...support the determination of the consequences of long-term cannabis use through concentrated research, especially among youth and adolescents... support the modification of state and federal laws to emphasize public health based strategies to address and reduce cannabis use."

"The American Medical Association took a bold step today, and they should be commended," commented former Congressman Patrick J. Kennedy, SAM's co-founder. "By explicitly rejecting calls to neutralize their anti-legalization position, they are sending a loud and powerful message to state and local decision makers, the Federal government, and the general public that to be on the side of science is to oppose efforts to expand marijuana use and addiction."

Furthermore, several other elements in the report are consistent with SAM's pillars, including calls to support: "the availability and reduc[tion] (of) the cost of treatment programs for substance use disorders...a coordinated approach to adolescent drug education...community-based prevention programs for youth at risk to fund the Office of National Drug Control Policy... greater protection against discrimination in the employment and provision of services to drug abusers." The report sums up much of these policy initiatives as a public health approach to marijuana use, which SAM wholeheartedly supports.

The AMA report follows an American Psychiatric Association position paper released last week, which concluded: "There is no current scientific evidence that marijuana is in any way beneficial for the treatment of any psychiatric disorder. In contrast, current evidence supports, at minimum, a strong association of cannabis use with the onset of psychiatric disorders. Adolescents are particularly vulnerable to harm, given the effects of cannabis on neurological development."

About Project SAM (Smart Approaches to Marijuana)

Project SAM is a nonpartisan alliance of lawmakers, scientists and other concerned citizens who want to move beyond simplistic discussions of "incarceration versus legalization" when discussing marijuana use and instead focus on practical changes in marijuana policy that neither demonizes users nor legalizes the drug. SAM supports a treatment, health-first marijuana policy.

American Psychiatric Association Position

TITLE: Position Statement on Marijuana as Medicine

ISSUE:
The medical use of marijuana has received considerable attention as several states have voted to remove civil and criminal penalties for patients with qualifying conditions. Yet, on a national level, marijuana remains a schedule I substance under the Controlled Substances Act (CSA), the most restrictive schedule enforced by the Drug Enforcement Administration (DEA)1. The Food and Drug Administration (FDA), responsible for approving treatments after appropriate and rigorous study, additionally does not support the use of marijuana for medical purposes. This juxtaposition of practice and policy has prompted many professional medical organizations to issue official positions on the topic. This statement reflects the position of the American Psychiatric Association (APA) on the use of marijuana for psychiatric indications. It does not cover the use of synthetic cannabis-derived medications such as Dronabinol (Marinol), which has been studied and approved by the FDA for specific indications.

APA POSITION:

  • There is no current scientific evidence that marijuana is in any way beneficial for the treatment of any psychiatric disorder. In contrast, current evidence supports, at minimum, a strong association of cannabis use with the onset of psychiatric disorders. Adolescents are particularly vulnerable to harm, given the effects of cannabis on neurological development.
  • Further research on the use of cannabis-derived substances as medicine should be encouraged and facilitated by the federal government. The adverse effects of marijuana, including, but not limited to, the likelihood of addiction, must be simultaneously studied.
  • Policy and practice surrounding cannabis-derived substances should not be altered until sufficient clinical evidence supports such changes.
  • If scientific evidence supports the use of cannabis-derived substances to treat specific conditions, the medication should be subject to the approval process of the FDA.
  • Regarding state initiatives to authorize the use of marijuana for medical purposes:
  • Medical treatment should be evidence-based and determined by professional standards of care; it should not be authorized by ballot initiatives.
  • No medication approved by the FDA is smoked. Marijuana that is dispensed under a state-authorized program is not a specific product with controlled dosages. The buyer has no way of knowing the strength or purity of the product, as cannabis lacks the quality control of FDA-approved medicines.
  • Prescribers and patients should be aware that the dosage administered by smoking is related to the depth and duration of the inhalation, and therefore difficult to standardize. The content and potency of various cannabinoids contained in marijuana can also vary, making dose standardization a challenging task.
  • Physicians who recommend use of smoked marijuana for “medical” purposes should be fully aware of the risks and liabilities inherent in doing so. Item 2013A2 4.B Assembly November 8-10, 2013 Attachment #1

BACKGROUND INFORMATION:

Medical Indications for Marijuana as Medicine:

Much of the evidence supporting marijuana use for non-psychiatric medical diagnoses remains anecdotal. The indications with the most evidence include: severe nausea and vomiting associated with cancer chemotherapy2, cachexia associated with Acquired Immune Deficiency Syndrome (AIDS)3, spasticity secondary to neurological diseases such as muscular sclerosis4, management of neuropathic pain5, and rheumatoid arthritis6. Several medical organizations have issued statements regarding indications for marijuana as medicine based on scientific evidence.

Contribution of Marijuana to Psychiatric Illness:

There is currently no scientific evidence to support the use of marijuana as an effective treatment for any psychiatric illness. Several studies have shown that cannabis use may in fact exacerbate or hasten the onset of psychiatric illnesses, as evidenced by both international trials and meta-analyses7-9. This includes the contribution of marijuana to symptoms of mood disorders, anxiety and psychosis, particularly in young adulthood10, 11. Cannabis use is associated with the emergence of mood disorders, particularly symptoms of bipolar disorder, among those with a family history of mood disorder12. Among those with major depressive disorder, co-morbid cannabis use is associated with increased rates of both suicidal ideation and attempts, raising grave safety concerns13. Among those with a predisposition to psychotic disorders, cannabis may hasten the emergence of both positive and negative psychotic symptoms14. The use of higher potency cannabis, for longer periods of time and with more frequency, is also associated with increased risk of psychosis15.

Several studies have demonstrated the link between marijuana use and mood, anxiety and psychotic disorders among adolescents. Cannabis use is associated with increased depression, suicidal ideation, use of other substances and risky behavior among adolescents16. Regular adolescent cannabis use is also associated with increased incidence of anxiety disorders17. Cannabis use significantly increases the risk of psychotic disorders among young adults18. Additionally, younger age of cannabis use is associated with an earlier onset of psychosis among those at risk19. Adolescents with a history of cannabis use tend to have higher severity of illness, lower psychosocial functioning, less insight, and longer courses of untreated psychosis compared to those without a history of cannabis use20. These findings are of particular concern as symptoms often persist into adulthood, and therefore cannabis use may increase the risk of lifelong symptoms and disability due to mental illness.

Serious Adverse Effects of Marijuana Use:

Cognitive and functional: Item 2013A2 4.B Assembly November 8-10, 2013 Attachment #1

 Marijuana use is associated with serious cognitive problems such as short-term memory deficits, poor concentration, attention, and information processing21. These impairments might be caused by neurotoxic effects of cannabis on the developing brain, the effects of which can lead to long-term cognitive problems well into adulthood22, 23. Adolescents with daily cannabis use show deficits in learning up to six weeks after stopping marijuana use24. This may contribute to significantly decreased academic achievement, including increased rates of school dropout, failure to enter higher education or attain higher degrees25. Among both adolescents and adults, cannabis significantly impairs driving, particularly as the drug affects automatic driving functions in a highly dose-dependent fashion 26. Cannabis use, particularly in combination with alcohol, greatly increases the risk of motor vehicle crashes due to effects on cognition and coordination27.

Addiction and burden of psychiatric illness:

Cannabis use is associated with an increased risk of developing a cannabis use disorder. Studies indicate that 9% of users become dependent on cannabis, and this number increases to 25-50% among daily users and to 1 in 6 among adolescents28. Adolescents remain at particular risk for cannabis use disorder, and can experience significant withdrawal symptoms including appetite changes, restlessness, irritability, depression, twitches and shakes, perspiration, and thoughts/cravings of cannabis29. Marijuana use is also associated with poorer outcomes among those with mental illness. Among individuals with schizophrenia, cannabis use is associated with poorer long-term clinical outcomes30. Individuals with psychotic illness may be more sensitive to both the psychosis-inducing and mood-altering effects of cannabis31. This may explain why even among those taking medications for psychotic disorders, cannabis use is associated with an increased risk of relapse into psychotic symtoms32.

Legalization of medical marijuana may reduce the perceived risks of use, the perception of societal disapproval, or the barriers to access, and potentially increase the incidence of the adverse events noted above.

Summary:

Given the gravity of concerns regarding marijuana as medicine, professionals in both neurology and psychiatry have emphasized the importance of prospective studies to understand the mechanisms by which cannabis functions, and its impact on mental health and behavior before instituting changes in practice and policy33,34.

Recommendations:

Given the general lack of evidence-based information among the public and membership, it behooves the APA to actively disseminate this position paper and background information in whatever way it seems fit to the public, policy-making entities and medical organizations.
