You seem to have started with one thing and ended with something completely different.
To start with the last one,i fully agree with your right to do what you please with your own body,including the ingestion of various kinds of drugs,be they more or less harmfull,barring of course doing any direct harm to others as a result.
That governments are the biggest drugdealers of all is no news to me and i have known and loved Bill Maher for some years already.
This is however a whole different thing from your previous post,where you seem to cast doubts on the harmfull effects of smoking tobacco...
There i have to disagree strongly.
All evidence points to smoking's negative effects far,far outweighing any
potential positive effects and saying otherwise is at the very least naive and at worst falsifying the 'record',so i'm afraid i have no choice but joining Janet with wagging the finger...
