A drug is anything that alters you--so this is a drug. The question is, "How fucking ridiculous is it to make it illegal". Lame.
It's like when I have been in So. Amer and chewed coca leaves to help with the altitude. It helps, it is natural, it is cheap. But our gov't would prefer to sell me some drug with side effects that I have to pay for the doctor visit, pay for the Rx, and spend a lot of time getting. Stupid. Just stupid.
