Which is why we punish people who misuse alcohol and drive drunk. We don't charge people with crimes for consuming alcohol in a responsible fashion. I think that's all that people are asking for. Making people into criminals for personal use of marijuana is silly.Beer is just as bad. Drunk drivers kill a lot of innocent people.
I bet with enough study we can isolate genetic traits associated with the tendency to get addicted to things and, through breeding programs, significantly reduce the number of people likely to develop drug addictions over time.
Also, marijuana is not addictive.
