i used to be addicted to marijuana alcohol cocaine heroin and methamphetamines but cant get free of the nicotine
Probably because it is not the nicotine that you are addicted to. The reason most approaches to smoking cessation fail, IMO, is that they are grounded in a number of myths, one of which is the extreme difficulty that people have quitting smoking is due to a drug addiction (nicotine), when the real story is much more complicated than that.
Treating an extremely habit forming product as though it were a drug addiction, as expected, fails terribly, as evidenced by the laughably poor performance of both medicinal and non-medicinal approaches to smoking cessation. It also explains why electronic cigarettes are extremely successful, in that they are the only approach that actually addresses the root of the problem, which is that smoking becomes a deeply engrained habit, albeit augmented by a relatively mild addiction, not to nicotine itself, but to a cocktail of chemicals.
The following links give a fairly good overview of some (but by no means all) of those myths:
