It is a drug, just not a hard drug. But just because it's labeled a drug doesn't make it any worse than any over the counter pain pill .

A drug is any substance that can be used to modify a chemical process or processes in the body, for example to treat an illness, relieve a symptom, enhance a performance or ability, or to alter states of mind. The word "drug" is etymologically derived from the Dutch/Low German word "droog", which means "dry", since in the past, most drugs were dried plant parts.
The word "drug" doesn't have to be a bad thing. Just most of the time people think it does. Especially people that seem to have a grudge with a substance they have never even tried lol.
