It’s not likely that these dunderheads have ever bothered to stop and ask why meth is rampant. But hey if multiple laws have failed, why not pass another? Why not just outlaw it altogether? If it works as well as prohibition, it should be a smashing success and readily available to all at a higher price leading to more crime.
Natural Ephedra was made illegal. Now the synthetic version could become prescription only. The trouble with the big government nanny state is that the good people are punished because of the idiots. Worse, the good people get to pay for the government to make a bad situation worse. Drug use is terrible. Government solutions to drug use are even worse.
Take the time to ask why people turn to drugs, and why they turn to particular drugs.
“In contrast with marijuana use, rates of other illicit drug use among ER [emergency room] patients were substantially higher in states that did not decriminalize marijuana use. The lack of decriminalization might have encouraged greater use of drugs that are even more dangerous than marijuana.”

You can’t criminalize everything preemptively. Government is always going to be behind the 8 ball on drug use. Shortly after banning one substance, drug pushers will create something else, perhaps even more dangerous, for those seeking drugs.
Wouldn’t it be nice if we could snap our finger and the drug problem would go away? Wouldn’t it be nice if we could pass a law and the drug problem would go away? It’s not that simple. Very few matters can be governed successfully. History clearly demonstrate drugs are a matter that can’t. Government can change the direction of sheep by scaring them in a different direction, but some will still stray on a new path, just as dangerous if not more so.
Update: It has been suggested that NORML isn’t the best source to quote. My goal wasn’t to quote NORML, but rather to reference studies that stimulate the thought that perhaps government involvement has unintended consequence that can be harmful. If someone can provide me with the actual study, I will update this post to link to it directly. The article link appears to work one time and not the next.
Don’t let a link be a distraction excuse. Do you own research and think critically on the matter. Government prohibition of alcohol failed and the drug war is failing.
There is a wealth of reading material available. Here are a few links to what was referenced above.
