I don't know...It happened to me to try it and it was okay. But I also think the fact that it is a totally different thing from the tobacco and that not everyone reacts the same way, especially if you acquire the "habit" of smoking it frequently.
I don't think is correct reasoning like: "if alcohol and tobacco are legal, then even marijuana" ..it is a dangerous argument. Certainly I think that marijuana is much less dangerous than alcohol, but..today marijuana, tomorrow what else? one day, it could become legal any real crap.
So, I support legalization for medical use.......for the rest I don't know. A part of me would say "yes" also for recreational use...but,the fact is that I don't trust people. One thing is smoking marijuana occasionally, another is smoking it regularly and without problems of any kind.
