Researchers are currently testing a vaccine meant to end cocaine addiction, but it might have the opposite effect. The drug, TA-CD, deadens the body's chemical response to cocaine after injection. In other words, it stops you from getting high. Which is good news for those of us who don't enjoy twitchy marathon dance sessions or Robin Williams' comedy. But it's potentially bad news for addicts, since many participating in the vaccine trials are drastically increasing their cocaine consumption in a desperate attempt to destroy the vaccine's defenses with brute force. Some test subjects were found to have ten times the normal level of cocaine in their system. Even those who didn't nearly overdose reported searching all over for new and different varieties of cocaine that might circumvent the vaccine. Which is really a sad situation, since the whole thing is so avoidable. Hey, guinea pigs: there's no vaccine for heroin yet. If you want, I know a guy who can hook you up. Better safe than sorry.
