If the drug is statistically safer than cigarettes or booze, you should legalize it unless you are prepared to begin a new Prohibition against cigarettes and booze. The assumed self righteousness of people who want their government approved addictions protected while threatening others using a less harmful, nonaddictive substance with no knock SWAT teams ready blow away your dog and you over a controlled vegetable, is hypocritical, reprehensible, And ludicrous in a so-called “land of the free”.
We don't live in a land of the free. We live in a land with statist politicians and their sympathizers who would love nothing more than to tell you that you can no longer eat fast food, that you can no longer fire people without good cause, and that you cannot own weapons to protect yourself. You are too irresponsible to consume drugs responsibly. DRUGS ARE EVIL, except those that we tax heavily. Those two are okay. You still can't use one of them in restaurants or public places, however. Nope.
