How many of you think that Marijuana should be legal?

I think it should only be legal for Medicinal purposes. But, People have other opinions about this.

For example, my friends say that they think it should be legal, because they think it is healthier than Cigarettes, Because it has less of that toxic stuff in them. This made them think to legalize Marijuana and make Cigarettes illegal. But, This is a bad idea, because People are still gonna sell cigarettes on the street corner :o.

But I disagree with this though, I mean, there has to be a reason why Cigarettes are legal, and Marijuana isn't. Also Marijuana has a more screwed up effect then Cigarettes...

Oh well, I want to see your opinions.
