One of the questions I often get when discussing marijuana legalization is about the harms of alcohol use versus the harms of marijuana use. I think the American Academy of Pediatrics summed up my thoughts on this matter best:
That alcohol and tobacco cause far more
harm in our society than marijuana is undeniable, but it does not follow
logically that yet a third addictive psychoactive drug (marijuana) should be
legalized. Many of the harms associated
with alcohol and tobacco use stem from the widespread acceptability,
availability, and use of these substances.
Still other harms result from lax enforcement of current laws regulating
their use or sale, especially to underage youth.
