Then don't smoke it. Scrambled eggs are a nice way of consuming cannabis and are what I had in mind when I wrote that no, cannabis is not harmful - because it in itself most definitely isn't.
Agreed, but you were responding to a comment that was implicitly referring to smoking it. Smoking was the context of the "Isn't it harmful?" question you were answering. It's responsible to clarify your answer, since the commentor was requesting enlightenment.
"There are 100,000 total marijuana smokers in the US, and most are Negroes, Hispanics, Filipinos and entertainers. Their Satanic music, jazz and swing, result from marijuana usage. This marijuana causes white women to seek sexual relations with Negroes, entertainers and any others." - Harry J. Anslinger, first US drug czar.
At the time when it was made illegal (early 30s): racist policies and pressure from various businesses. Now? Because of entrenched "tradition" within many reactionary legislatures.
I'd like to know, too. It changes slowly, fortunately, and more and more jurisdictions recognize cannabis as both a potent medicine and safe recreational drug.
No, it isn't.
Next question?
