MYTH: The Florida amendment proposes marijuana for only serious medical conditions, such as those suffering from cancer and AIDS.

FACT: The ballot summary states that medical marijuana is only for those with debilitating diseases, but the ballot definition states that it will be acceptable for “other conditions for which a physician believes that the medical use of marijuana would outweigh the potential risks for a patient.” This begs the question: what constitutes a debilitating disease? Other states with medical marijuana laws have considered migraines, anorexia, muscle spasms, and even menstrual cramps to be a debilitating disease that is treatable by marijuana—even though all of these conditions are treated by commonly accepted medical treatments.

MYTH: The Florida amendment requires a physician’s prescription to obtain medical marijuana from a medically controlled pharmacy.

FACT: No prescription is required to obtain medical marijuana.  A patient only needs a “physician certification” from a licensed Florida physician. Physician certifications are not formal prescriptions accepted by reputable pharmacies; they are simply written recommendations that can be used to buy marijuana at storefront dispensaries.

MYTH: The Florida amendment requires parental consent for a minor to obtain medical marijuana.

FACT: The amendment allows a teenager to get a recommendation for medical marijuana without the consent of a parent.  The amendment allows a teenager to get a recommendation for medical marijuana without the consent of a parent. Although Florida law requires consent when treating minors, the amendment gives immunity (both civil and criminal) to physicians who issue a recommendation to use marijuana. Other states have tighter requirements when it comes to recommending to minors, such as requiring the physician to explain the risks and harms associated with marijuana use and/or multiple physician assessments.

MYTH: Smoking marijuana is the only way to receive the medicinal properties of the plant.

FACT: Some components in marijuana have medicinal properties, but we shouldn’t smoke the plant in order to derive those benefits; just as we do not smoke opium to get the benefits of morphine.  In states with medical marijuana laws, the average user is a male in his 30s with no terminal illness and a history of drug abuse (TJ O’Connel, Long term marijuana users seeking medical cannabis in California).  Less than 5% of registered users in states allowing medical marijuana have cancer or AIDS (Who’s Really Smoking, Save Our Society From Drugs, April 2014 ).  Residents of states with medical marijuana laws have abuse and dependence rates nearly twice as high as states with no such laws (M. Cerda, Medical marijuana laws in 50 states).

MYTH: Marijuana is harmless.

FACT: Today’s marijuana is far more potent than in decades past. In the 1960s and 70s, THC levels of marijuana smoked by baby boomers averaged around 1%, increasing to just under 4% in 1983, and almost tripling in the subsequent 30 years to around 11% in 2011. Regular marijuana use, started in adolescence and continued into adulthood, can result in a loss of up to 8 IQ points. (Meier, et al. Persistent cannabis users show neuropsychological decline from childhood to midlife.)

MYTH: Marijuana legalization will help the economy.

FACT: Marijuana legalization will increase public costs. For every $1 in alcohol and tobacco tax revenue, society loses $10 in social costs from accidents all the way to health damage (National Institute on Alcohol Abuse and Alcoholism). States such as Colorado have projected tax revenue of $134 million for the fiscal year but have only produced 3.5 million in the first month, prompting the Governor to ratchet back his projection to $20 million.
