Myth Smoked Marijuana is Medicine 20 Legalization behind the smokescreen “We will use [medical marijuana] as a red-herring to give marijuana a good name.” —Keith Stroup, head of NORML to the Emory Wheel, 1979 • Advocates have pushed their agenda through “medicine by popular vote” rather than the rigorous scientific testing system devised by the FDA. Emory Wheel Entertainment Staff, 6 February 1979 21 Is Marijuana Medicine? NO: SMOKED OR INHALED RAW MARIJUANA IS NOT MEDICINE YES: THERE ARE MARIJUANA-BASED PILLS AVAILABLE AND OTHER MEDICATIONS COMING SOON MAYBE: RESEARCH IS ONGOING Compassionate care or increased access to marijuana? <5% • Less than 5% of card holders are cancer, HIV/AIDS, or glaucoma patients • Average user: 32 WM, no illness Bottom Line We don’t smoke opium to get the effects of morphine. So why would we smoke marijuana to get its potential medical effects? Cannabis-Based Medicines Research on the efficacy of cannabinoids is not focused on raw/crude marijuana, but in the individual components that may have medical use. Sativex is in the process of being studied (phase III trials) Approved in Canada and across Europe Administered via an oral spray 25 Epidiolex™ 98% pure CBD Some effectiveness for seizures Many versions on market which are not purified or standardized 26 Myth The Legality of Alcohol and Tobacco Strengthen the Case for Marijuana Legalization 27 Alcohol and Tobacco: A Model? • Use levels for alcohol and tobacco are much higher than marijuana • Industries promote addiction and target kids Schiller JS, Lucas JW, Peregoy JA.

Morbidity and Mortality Weekly Report 2011;60(33):1207–12 28 Will legalization diminish the power of cartels and the black market? • In a legal market, where drugs are taxed and regulated (for instance to keep THC potency below a certain level or to prevent sale to minors), the black market has every incentive to remain • Would legalizing marijuana would not deter these groups from continuing to operate?

Myth Portugal and Holland Provide Successful Examples of Legalization 36 Neither Holland nor Portugal have legalized ANY drug 37 Legalization: Experience elsewhere? No modern nation has tried legalization, though most Western countries do not imprison people for simple marijuana possession. • Use rates in the Netherlands, Portugal, and Italy in the last 10 years are lower for some drugs and higher for others. • The Dutch experienced a three-fold increase in marijuana use among young adults after commercialization expanded. 38 Portuguese policy In 2001, Portugal changed policy to send users with small amounts of drugs to “dissuasion panels” – social worker panels who refer individuals to treatment, administer fine, etc. Portugal also implemented robust treatment plan 39 Results are mixed • Youth use has increased since 2001 • Deaths have gone down • The impact of the policy unclear, despite extreme rhetoric 40 Dutch policy The Dutch established the Non- enforcement Policy in 1976 and saw the birth of “Coffee Shops” 41 Results • Experienced a three-fold increase in marijuana use among young adults • Before Non-Enforcement, the Dutch always had lower rates of drug use than the US.
