Toxicologist warns of dangerous symptoms from K2

ST. LOUIS — A Saint Louis University professor of toxicology is warning of dangerous symptoms among teenagers who smoke a substance that mimics the effects of marijuana.

Anthony Scalzo said he has seen more than 20 cases of teenagers having hallucinations, severe agitation, elevated heart rates and other reactions to the substance known as K2 or "fake weed."

Scalzo said the symptoms suggest K2 affects users' cardiovascular systems.

K2 is an unregulated mixture of dried herbs that is purported to give a safe high similar to marijuana.

The Missouri House was scheduled to debate a bill outlawing K2 Wednesday.

If it weren't for the prohibition of marijuana, folks would not buy k2 incense alternatives. Why would they? If people had legal access to the real deal they would not be hunting down k2 herb and the like. Just as the government has wasted endless resources chasing down marijuana, now they are going to do the same with this incense stuff. It is ridiculous and wasteful in more ways than one. How long have these products been banned, and there are still places advertising legal everywhere products like those found at .
