I’m a little confused because I thought this thread was about marijuana, not drugs in general.
There are three main arguments against the legalization of marijuana: addiction, health risks, and crime.
Marijuana has not been proven physically addictive in any study. It does not alter brain chemistry. It has been proven only psychologically addictive. As far as that goes, I’m psychologically addicted to reading - I need to be in the middle of at least two books at any given time to be comfortable with the status of my brain.
Marijuana use has never been listed as the cause of death on any death certificate - there is no documented case of a marijuana overdose. Thus listing the threat of death as a reason for continued criminalization is not logical. It is damaging to the body, but far less so than alcohol or tobacco, and its use has many benefits whereas alcohol and tobacco do not. Marijuana is prescribed to many chemotherapy and anorexia patients to establish an appetite and lessen pain, and it has been proven to benefit glaucoma sufferers.
As far as crime is concerned, I don’t know a single stoner who would rob or kill anyone for more weed. Again, there is no physical addiction that would cause such desperation. I do, however, know recreational marijuana smokers that are vice-presidents of top corporations, successful lawyers, and doctoral candidates. (I have not seen any statistics on crime and marijuana, so personal experience will have to do. As I don’t believe any of the opposition here have seen any studies on this subject either, nor do they, admittedly, have any personal experience, experiential support should suffice.)
In addition, marijuana plants restore nutrients to the soil that have been depleted through farming, which is why it was prevalent during the 19th century in America. Also, the stalks can be used to make hemp, one of the strongest natural materials. This use alone would help to revitalize the ever-diminishing farming culture in the United States, and is an inherent benefit to decriminalization.
I have yet to hear a rational argument against the legalization of marijuana, but misinformation on the part of the media and fear on the part of the general populace tend to stifle logic. If anyone has a well-supported case in favor of the illegality of marijuana - not other drugs - I would be very interested in hearing it.
