I’m going to tackle something a little different. For some reason, the prohibition of marijuana has caught my attention recently. I was listening to NPR and there was a story about it, the topic also appeared in a documentary I was watching recently. Either way, I’ve been thinking quite a bit about a particular aspect of it, and I want to present some thoughts that I had.
To give you a quick run down, the de-criminalisation of marijuana is an attempt to make the use of the drug legal. This, for many, is a means of attempting to prevent, or at least significantly reduce the use of the drug. Now, I’m not going to go into the issue because its a complex and multifaceted debate and both sides have comprehensive arguments. I’ll let you do your own research. What I do want to do is focus, albeit obliquely, on one aspect of the health issue.
Part of the debate revolves around the harmful health effects of marijuana use. The argument is that marijuana, like other drugs, pose significant health risks, and should therefore be illegal. I have no doubt that marijuana poses health risks. It is a harmful substance that effects mental health, causes different forms of cancer, and can cause heart complications. I wouldn’t argue that it isn’t harmful. But here’s the thing. If we follow this argument to its logical conclusions, we’d be criminalising the use of a heck of a lot of substances, the first of which would be tobacco and alcohol.
Tobacco
Smoking is a major risk factor for heart attacks, strokes, chronic obstructive pulmonary disease (COPD), emphysema, and cancer (particularly lung cancer, cancers of the larynx and mouth, and pancreatic cancer). The World Health Organization estimate that tobacco caused 5.4 million deaths in 2004 and 100 million deaths over the course of the 20th century. The US Center for Disease Control and Prevention describes tobacco use as “the single most important preventable risk to human health in developed countries and an important cause of premature death worldwide.”
Alcohol
Alcohol consumption is correlated with an increased risk of developing alcoholism, coronary heart disease and cardiovascular disease, malabsorption, chronic pancreatitis, alcoholic liver disease, dementia, cancer, stroke and damage to the central nervous system and peripheral nervous system. Long-term use of alcohol in excessive quantities is capable of damaging nearly every organ and system in the body. This is not including other effects such as injuries, violence and fetal damage.
Now, considering that there is no conclusive evidence which suggests that the effects of marijuana outweigh those of alcohol or tobacco, why is the argument made from a health perspective for the prohibition of marijuana? And where do we stop? What about fast food? We should make big macs illegal. Hydrogenated oil and trans-fats ought to be outlawed, and with much more haste than marijuana. The obesity epidemic is killing us, not to mention the strain on the health care system.
Now, don’t get me wrong, the social and health-related effects of alcohol and tobacco (and even fast-food) still apply to some extent to marijuana, and I’m certainly not condoning the use of the drug. My argument is simply that from a health perspective, the prohibition of marijuana is illogical. There are legal substances with proven health consequences that far outweigh that of marijuana.
I don’t think we need to prohibit the use of alcohol, tobacco, or fast-food. At least in the near future, it would be impossible. We’d see an almost unimaginable increase in illegal trade of those substances. But looking at the issue from this perspective gives us an interesting insight into the way in which the prohibition of a substance stigmatises it, particularly when that substance has no more harmful health effects than its legal counterparts.
To be continued…?
