How should it be classified?
Like alcohol or tobacco.
Here's some entertainment for you:
John Stossel
"...The son of Duke "Death Penalty for Drug Kingpins" Cunningham, R-Calif., was convicted for possession of 400 pounds of marijuana. Mother Jones reported that in court, the congressman cried and pleaded for mercy, explaining that his son "has a good heart. He works hard." The congressman — who denounced "soft-on-crime liberal judges" and railed against "reduced mandatory-minimum sentences for drug trafficking" (and who himself is now in prison for taking bribes) — won for his son the mercy he fought to deny others: half the federal "mandatory" minimum sentence..."
"...All too often, officials protect themselves and their families from the punishments they set up for the rest of us. Using drugs might be a crime for you, but it's a joke for someone named Bush or Clinton.
Our rulers make laws to control and punish you and your family for doing the very acts they flaunted in their youth.
Smoking pot is not a big deal. If the politicians have enough common sense to know that their lives shouldn't be ruined over a little drug use, they should also have enough common decency to recognize that neither should anyone else's."
