And if you hadn't already heard, you would never guess who is heading it.  The WaPo's Reliable Source bloggers Roxanne Roberts and Amy Argetsinger have this post.

For a generation of liberals, legalization of marijuana has become a harmless -- if not inevitable -- issue.

Not for Patrick Kennedy. The former Rhode Island congressman and scion of the famed Democratic dynasty has taken a surprising turn to the right in this debate.

"Marijuana destroys the brain and expedites psychosis," he told us Tuesday. "It's just overall a very dangerous drug."

After 16 years in Congress, Kennedy, 45, left Washington two years ago and began traveling the country to see how legislation he spearheaded on mental health is being implemented. He's become convinced that marijuana ("the biggest single threat to the cause I care so much about") is as destructive as alcohol and tobacco and just launched Project SAM (Smart Approaches to Marijuana) to shift the debate from legalization to prevention and treatment -- despite what appears to be a growing social acceptance of the drug.

On the SAM website, I note that Mr. Kennedy et al. share my view that a legal industry that promotes pot the way tobacco has been promoted is a nightmare.
