It's one thing to say that drugs are dangerous. It's quite another to suggest that the decision to legalize/not legalize should be based on that danger.
"Walters was in Las Vegas to convince Nevadans that legalizing the possession of small amounts of marijuana is a bad idea. [...] He said baby boomers might think it's harmless that their kids are experimenting with marijuana as they did. He said the marijuana sold to teenagers today is more potent and dangerous than the strain their parents used when they were young." - Las Vegas Review-Journal, July 25, 2002
