The way I look at it is...
Why do we have legal alcohol, and have illegal pot? I bet the reason it is illegal has something to do with being able to grow pot in your closet and Uncle Sam would have a hard time making $$ from it. Beer, wine, whiskey etc. are a little harder to make thus easier to regulate and tax.
We spent billions to keep pot off the street and it has done nothing to stop the trade. I find it hypocritical to spend money in the schools to have the DARE program, then when the bell ring 20% of the kids go to the nurses stattion to get Ritalin.
Teacher- "Kids don't do drugs!!!! Johnny go get your Ritalin after the bell rings."
I am all in favor of keeping Cocaine, Crack, Heroin, Meth etc. illegal.
BTW... I am am still intolerant.
