That would be fucking horrible for us. Know how many more cops would be taking peoples stashes if they had to try before they bust.
in all honesty I think it would be a great idea because they wouldn't be such dicks when dealing with stoners. I also think that it would make herb a doorway drug because then they would have to try crack, heroin, speed, shrooms, acid, peyote(if they are on indian land)....etc etc
