what i think whoever said nicotene in more dangerous than harder drugs meant that,

some people belive it is harder to kick the habit of smokeing than to quit other things
Well that and the fact that nicotine is one of the deadliest natural poisons known to man.

I think people are getting off-topic though, those who are saying they are against heroin, meth, cocaine etc. that has little to do with this natural vs. synthetic argument. All of the cocaine on the street was made naturally via the erythroxylum coca.
