Facts on the Emerging Science on the Effects of Marijuana

/By

Marijuana is one of the most hotly debated drugs of our time, according to Kevin Sabet, PhD, Policy Consultant and Assistant Professor, University of Florida. He says that while sifting through the rhetoric about the drug can be difficult, it is important to know what the research has established. There is now a plethora of scientific studies about the use of the drug and its public health implications.

According to Dr. Sabet, we can say with some certainty that marijuana use is significantly linked with addiction, heart and lung complications, mental illness, car crashes, IQ loss and poor school outcomes, poor quality of life outcomes and poor job performance.

In the first of a two-part series of white papers to outline the facts about the drug, Dr. Sabet discusses:
•    Marijuana and the brain
•    What makes marijuana harmful? Three simple letters: T-H-C
•    Marijuana and addiction
•    Marijuana and driving
•    Marijuana use and performance at school and on the job

    This is not a very nuanced article. Two examples: The author claims that “The Netherlands has the highest rate of marijuana addiction in Europe”. This is simply not supported by the original article, which states that the Netherlands has the highest TREATMENT rates, but that this is likely due to greater availability. Indeed, the authors conclude “Dutch citizens use cannabis at more modest rates than some of their neighbors, and they do not appear to be particularly likely to escalate their use relative to their counterparts in Europe and the United States. Second, while it is true that “a widely-cited article in the British Medical Journal from 2012 concluded that marijuana use doubles the risk of car crashes”, the increase in risk is comparable that seen at alcohol BAC =.02 – .049, or to being a 16-20 year old male who has consumed no alcohol.

    These are excellent facts, but the crowd who usually are involved in this activity consider themselves scientists and philosophers, so it may be hard to convince them. I am convinced that the consumption of marijuana is their religion.

    well this may be true but isnt it also true that all the prescriptions that dr.s’ write for pain killers and nerve pills are just as bad for your health if not worse!

    Even if all of Dr. Sabets’ correlations were true (which they are not) should we now list all the negative consequences and health risks directly related to incarceration and prohibitionist policies?

    the only bad part about this is the silly notion that many users quote in support of their use, “MJ has never ever killed anyone!”

    Dear Dr. Sabet thank you so much for this wonderful piece. Now we have to get the facts you have written to our policy makers. I can’t wait for part two.

    Thank you Dr. Sabet, This is going to be very helpful for informing our school district’s Health and Wellness Program, as well as for informing our Chemical Health Policies. Jody Hensley, Westborough, MA School Committee
