Nicotine, derived from the leaves of the tobacco plant, is the active chemical in cigarettes, cigars, chewing tobacco, snuff or snus. In the past, tobacco was commonly smoked as ‘roll-your-owns’ or pre-made cigarettes (AKA Durry, ciggy, rollie, smokes, darts). However, vaping (heating a liquid, usually containing nicotine, to produce a vapour) has also become popular in the last few years.
Nicotine brings feelings of relaxation within ten seconds, but this lasts only a few minutes, leaving a craving for more to maintain the pleasurable feeling and prevent withdrawal. Used over a long period of time, the smoke from cigarettes can cause severe respiratory and other physical damage.
