The only remaining argument the anti-marijuana people seem to have, is that there is a tiny fraction of increased mental illness risk associated with using marijuana during one's developmental years. Needless to say, it is one of the dumbest arguments ever constructed. It's like saying, because cars are dangerous when driven by 10 year-olds, it should be illegal for anyone to drive a car. Not to mention the fact that it is only an increased risk, and a very small increase at that. You could make a counter-argument that if you use marijuana during your developmental years, you will become President of the United States.

It's also bizarre to suggest that because something has the potential to cause illness or injury, it should be illegal. That's like saying sports should be illegal, because so many athletes sustain injuries. Furthermore, imprisonment is also an injury, so how is it an improvement to replace one injury with another? Either you're injured in the sport, or you're injured through imprisonment. It doesn't make sense. If the idea is to reduce illness and injury, then imprisoning and fining has the opposite effect.

The simple fact is that the anti-marijuana people are wrong. This is not a matter of your personal beliefs, this is a matter of the fact that 2+2=4. No matter what bullshit propaganda or nonsense reasoning you devise, 2+2 will always = 4. You're wrong, accept it, change the fucking laws, and let's move on to another issue.
