Think thats the furthest we are ever going to see in which animation and drugs really connected.
Warnings for drugs are everywhere. Movies come out yearly depicting the bad habits and death tolls of drug abuse. They advertise on television, brochures, hospitals, dental offices, billboards.... It is very rare for someone near you to really say "hey this is good stuff, makes you live longer" and give a :thumbs up:.
I really don't see the point in making an anime based on that, since you can see bad influences and habits throughout just about any anime title there is. Make a story thats cool, graphics are amazing, such and such.. well I am pretty sure people have thought of that idea. They probably havn't made it, because making a series promoting anti-drug won't be that popular.
I honesty don't think that a large majority would really care to see there entertainment tainted by the ever increasing virus that is reality. It is a poor subject to work from. People see warning signs all over the place; and personally, if they can't figure out the life threatening outcomes of dealing with drugs.. than they are either blind or retarded. You gotta be stuck pretty far back in time to not see or hear anything about the subject. If they choose to not pay attention, than that is the path they follow and probably need to get burned to learn the lesson of "not to play with matches."
Nobody really cares to see that. Or nobody can come up with a really smashing series that involves that crap.
