Also, I think another reason that hinders its legalization is that it would be almost impossible to control. It is easily grown, in sand, mud, soil, hell rocks and never mind hydro
I also do not understand how alcohol can be legal and pot not. I have the "pleasure" of slinging drinks and I gotta say, booze turns 50% of the people into instant A-hole.
I know I would much rather be passing a bong at a hash bar than giving 21yr olds a few drinks w/shots=bad news.
