Marijuana Is Harmful: Debunking 7 Myths Arguing It's Fine

Myth No. 1: “Marijuana is harmless and non-addictive”
No, marijuana is not as dangerous as cocaine or heroin, but calling it harmless or non-addictive denies very clear science embraced by every major medical association that has studied the issue. Scientists now know that the average strength of today’s marijuana is some 5–6 times what it was in the 1960s and 1970s, and some strains are upwards of 10–20 times stronger than in the past—especially if one extracts THC through a butane process. This increased potency has translated to more than 400,000 emergency room visits every year due to things like acute psychotic episodes and panic attacks.
Mental health researchers are also noting the significant marijuana connection with schizophrenia, and educators are seeing how persistent marijuana use can blunt academic motivation and significantly reduce IQ by up to eight points, according to a very large recent study in New Zealand. Add to these side-effects new research now finding that even casual marijuana use can result in observable differences in brain structure, specifically parts of the brain that regulate emotional processing, motivation and reward. Indeed, marijuana use hurts our ability to learn and compete in a competitive global workplace.
Additionally, marijuana users pose dangers on the road, despite popular myth. According to the British Medical Journal, marijuana intoxication doubles your risk of a car crash.
Myth No. 2: “Smoked or eaten marijuana is medicine.”
Just like we don’t smoke opium or inject heroin to get the benefits of morphine, we do not have to smoke marijuana to receive its medical effects. Currently, there is a pill based on marijuana’s active ingredient available at pharmacies, and almost two-dozen countries have approved a new mouth spray based on a marijuana extract. The spray, Sativex, does not get you high, and contains ingredients rarely found in street-grade marijuana. It is likely to be available in the U.S. soon, and today patients can enroll in clinical trials. While the marijuana plant has known medical value, that does not mean smoked or ingested whole marijuana is medicine. This position is in line with the American Medical Association, American Society of Addiction Medicine, American Glaucoma Foundation, National MS Society, and American Cancer Society.
Myth No. 3: “Countless people are behind bars simply for smoking marijuana.”
I wholeheartedly support reducing America’s incarceration rate. But legalizing marijuana will not make a significant dent in our imprisonment rates. That is because less than 0.3 percent of all state prison inmates are there for smoking marijuana. Moreover, most people arrested for marijuana use are cited with a ticket—very few serve time behind bars unless it is in the context of a probation or parole violation.
Myth No. 4: “The legality of alcohol and tobacco strengthen the case for legal marijuana.”
“Marijuana is safer than alcohol, so marijuana should be treated like alcohol” is a catchy, often-used mantra in the legalization debate. But this assumes that our alcohol policy is something worth modeling. In fact, because they are used at such high rate due to their wide availability, our two legal intoxicants cause more harm, are the cause of more arrests, and kill more people than all illegal drugs combined. Why add a third drug to our list of legal killers?
Moreover, marijuana legalization will usher in America’s new version of “Big Tobacco.”
- Already, private holding groups and financiers have raised millions of start-up dollars to promote businesses that will sell marijuana and marijuana-related merchandise.
- Cannabis food and candy is being marketed to children and are already responsible for a growing number of marijuana-related ER visits. Edibles with names such as “Ring Pots,” “Pot Tarts,” and “Kif Kat Bars” are inspired by common children candy and dessert products.
- Profitable companies such as Medbox (based in California) has stated its plans to open marijuana vending machines containing products such as marijuana brownies. The former head of Strategy for Microsoft has said that he wants to “mint more millionaires than Microsoft” with marijuana and that he wants to create the “Starbucks of marijuana.”
Unfortunately, we can’t expect societal financial gain from marijuana legalization. For every $1 in revenue the U.S. receives in alcohol and tobacco taxes, we spend more than $10 in social costs. Additionally, two major business lobbies—Big Tobacco and the Liquor Lobby—have emerged to keep taxes on these drugs low and promote use. The last thing we need is the “Marlboroization of Marijuana,” but that is exactly what we would get in this country with legalization.
Myth No. 6: “Portugal and Holland provide successful models of legalization.”
Contrary to media reports, Portugal and Holland have not legalized drugs. In Portugal, someone caught with a small amount of drugs is sent to a three-person panel and given treatment, a fine, or a warning and release. The result of this policy is less clear. Treatment services were ramped up at the same time the new policy was implemented, and a decade later there are more young people using marijuana, but fewer people dying of opiate and cocaine overdoses. In the Netherlands, officials seem to be scaling back their marijuana non-enforcement policy (lived out in “coffee shops” across that country) after witnessing higher rates of marijuana use and treatment admissions there. The government now only allows residents to use coffee shops. What all of this tells us about how legalization would play out in the U.S. is another point entirely and even less clear.
Myth No. 7: “Prevention, intervention, and treatment are doomed to fail—So why try?”
Less than 8 percent of Americans smoke marijuana versus 52 percent who drink and 27 percent of people that smoke tobacco cigarettes. Coupled with its legal status, efforts to reduce demand for marijuana can work. Communities that implement local strategies implemented by area-wide coalitions of parents, schools, faith communities, businesses, and, yes, law enforcement, can significantly reduce marijuana use. Brief interventions and treatment for marijuana addiction (which affects about 1 in 6 kids who start using, according to the National Institutes of Health) can also work.
And one myth not found in the book: “Colorado and Washington are examples to follow.”
Experience from Colorado’s recent legalization of recreational marijuana is not promising. Since January, THC-positive test results in the workplace have risen, two recent deaths in Denver have been linked to recreational marijuana use, and the number of parents calling the poison control hotline because their kids consumed marijuana products has significantly risen. Additionally, tax revenues fall short of original projections and the black market for marijuana continues to thrive in Colorado. Though Washington State has not yet implemented its marijuana laws, the percentage of cases involving THC-positive drivers has significantly risen.
Marijuana policy is not straightforward. Any public policy has costs and benefits. It is true that a policy of saddling users with criminal records and imprisonment does not serve the nation’s best interests. But neither does legalization, which would create the 21st century version of Big Tobacco and reduce our ability to compete and learn. There is a better way to address the marijuana question—one that emphasizes brief interventions, prevention, and treatment, and would prove a far less costly alternative to either the status quo or legalization. That is the path America should be pursuing—call it “Reefer Sanity.”
