Nicotine is an addictive drug like heroin, amphetamine or cocaine. Addiction to tobacco leads to significant failure rates in programmes for smoking cessation. The alpha(4)beta(2) and alpha(7) nicotinic acetylcholine receptors (nAChRs) and CB1 cannabinoid receptors play an important role in nicotine addiction.
