Marijuana: An Overview
Let me start off by saying that I am not a doctor, nor do I have any advanced degrees in pharmacology, however I am currently studying psychiatry and focusing on drugs and addiction. As a result, I have a great wealth of knowledge when it comes to marijuana so I hope to provide an overview of some hot topics concerning marijuana.
First off in response to the original question: Marijuana is illegal under federal law for any use, be it medical or recreational. This means that federal officials can arrest anyone in possession of marijuana, and it also means some other things for example you cannot ship marijuana through the mail because the mail system is federally controlled, even within a state where marijuana has been legalized. The way around this is in states where it has been legalized, state and local police cannot arrest you for possession because according to the laws under which they operate, marijuana is legal. Technically an FBI agent could drive to Colorado and arrest anyone with marijuana, but this is very unlikely to happen because federal agents would not concern themselves with such a minor offense.
Is it a good thing that marijuana is becoming more and more legal? Yes and no. First of all, there is no denying that marijuana is bad for you. This is a scientific fact and simply cannot be refuted. That said, there are tons of legal things that are bad for you as well, such as tobacco, alcohol, fast food, a sedentary lifestyle…the list goes on and on. From this, I can conclude that it is at least inconsistent with current laws to make marijuana illegal BASED SOLEY on the fact that it is harmful to your health.
How bad is it for you? That's tough to answer but I can give some examples. The main factor is how and how often one uses marijuana. Marijuana smoke is carcinogenic, just like cigarette smoke, meaning it causes cancer, but smoking marijuana once will not increase you chances of getting cancer by any measurable amount, it depends on how much you smoke. For example, cigarettes cause more cancer than marijuana because 1) more people smoke cigarettes and 2) people who smoke tobacco smoke much more (gram for gram) than people who smoke marijuana, which leads us to our next point: addiction.
It is a myth that marijuana is not addictive. People get addicted to marijuana, there is irrefutable scientific and anecdotal evidence to confirm this. Its really very obvious, anything that causes enjoyment or pleasure has the potential to be addictive the important factors are going to be HOW addictive it is and the consequences of that addiction. Compared to other recreational drugs (including alcohol and tobacco), marijuana is significantly less addictive. This is because marijuana dependence is rare, it takes a lot of marijuana to create a physical dependence to it where one would experience withdrawal symptoms if they were to stop abruptly. Because of this, marijuana's addiction potential is mostly psychological. Bear in mind however that psychological addiction is more often than not the most difficult aspect of addiction to treat. Physical dependence can be treated by simply weening off a drug in detox period, however psychological addiction requires a good amount of quality psychotherapy and self will, and in some cases drugs as well. All of this said, its relatively rare to find someone with only an addiction to marijuana. Most marijuana addictions are part of a poly drug addiction. The consequences of a genuine marijuana addiction more or less parallel a tobacco addiction, however marijuana cause more psychological problems so its safe to say marijuana addiction is more harmful than tobacco addiction.
A common thing said in support of marijuana is "Why doesn't the government just legalize it so they can tax it?" While this seems like a good idea, there are a number of problems with it. For one, its takes a lot to completely reverse a federal law. For marijuana, this would require scientific studies on both the health and social effects of legalizing marijuana and years of debate, right now out government simply has more important things to focus on like debt, poverty, health care, and the war. Also, it would be no easy task to set up a system for distributing and taxing marijuana, we are talking about a huge multimillion dollar infrastructure plus the manpower to run it. Also, we can't forget that there are still many people that strongly oppose marijuana, so even if the government were able to set all this up it would still need to pass a vote. The voices advocating its legalization are louder than those opposing it, but this is probably because the people opposing it already have what they want, so its hard to tell what the majority of people really want. In conclusion, while its valid to say that the government would eventually profit off marijuana's legalization, we cannot ignore the tremendous resources such a feat would require.
As a side note, we have to remember that if the government were to legalize and tax marijuana, it would still be smuggled into the country. In order for the government to make any significant amount of money off taxing marijuana, it would probably be more expensive than it is now, so people would still have incentive to buy from illegal sources.
So to wrap everything up:
1) Marijuana like all other recreational drugs, can be addictive and harmful.
2) Legalizing it federally is a big feat, its not something that can be brought about by a simple vote.
3) Legalizing marijuana does not necessarily eliminate the problems caused by its illegality.
My opinion: I think that if it were possible to go back in time before marijuana was made illegal, it would be a good idea to keep it legal. Unfortunately this is not possible. I actually think ALL drugs should be legal. I believe, and there is evidence to back me on this, that more problems are caused by making drugs illegal than by making them legal. The basic reason for this is the following: People will always try to do what they want. If someone wants to use drugs, they will find a way to do so whether its legal or not. BY making drugs illegal, its harder for people to get drugs but not hard enough to be justified as a significant deterrent. Because of this, a large portion of crime in this country is built around the drug trade, and a large portion of prisons are populated by non-violent drug offenders. The increase in drug health related problems that would be caused by making drugs legal would be far less harmful than the problems we are currently facing due to the illegality of drugs.
And finally, all this is speculation. We have no real life model of a country that had drugs illegal and then decided to legalize them, so its hard to be sure of what would actually happen. Everything I said is just one side of the story, there is evidence on both sides of the coin I simply believe this side to be better.
