Hey guess what:  teens currently get weed illegally from drug dealers;  who knows what that weed is laced with,  and being around some of these dealers is probably not the safest thing either.  I'd much rather teens pay an adult to get them weed from a government controlled store, where you know exactly what is in the weed, than to get  potentially dangerous stuff from a shady dealer.  The kids will get their weed, just like they get alcohol, lets no bury our heads in the sand.
