Addiction to nicotine does not happen quickly, after using tobacco once or twice; it develops over time. Most smokers go through a series of steps from experimentation to regular use on their way to becoming addicted. Particularly in the industrialized countries, most people addicted to nicotine initiated smoking during adolescence. Since a typical smoker takes 10 puffs on each cigarette, a person who smokes a pack of cigarettes a day (20 cigarettes per pack) will receive 200 doses of nicotine daily. No other drug is dosed at such a high frequency. This conditioning, in addition to the presence of nicotine, is critical to the addiction process.

Sets of patches come in three sizes: the 24-hour patch has dosages of 21 mg, 14 mg and 7 mg, and the 16-hour patch has dosages of 15 mg, 10 mg and 5 mg.Half of adult Indigenous Australians (50%), were current daily smokers.Smoking was associated with poorer health outcomes among Indigenous Australians. Nicotine is as addictive as heroin and cocaine, and it has the paradoxical effects of being a stimulant and a depressant.
