Overview: Most smokers don't think of themselves
as drug addicts, but that's what they are. In fact, the drug
they're addicted to -- nicotine -- is one of the most powerfully
addictive substances in the whole chemical kingdom. That's why
so many smokers (and users of other nicotine-based products)
find it so hard to stop, in spite of the many risks linked to
Actions/Effects: Absorbed via the alveoli in the lungs or the mucous membranes in the nose and mouth, nicotine unleashes a rapid release of adrenaline, which increases blood pressure and heart rate, and steps up activity of the neurotransmitter dopamine, causing a range of other effects. To addicted users, nicotine triggers both stimulant and calming effects.
Risks/Side Effects: Early side effects include dizziness and nausea until users develop tolerance to nicotine's drug effects. Most of the long-term risks associated with nicotine use are linked to the tars, toxic gases, and particulates in tobacco smoke, which can cause cancer, heart disease, emphysema, and other diseases.
Medical Uses: Recent research has shown that small doses of nicotine delivered by skin patches may help those with Alzheimer's disease and attention deficit disorder (ADD) maintain concentration and improve short-term memory.
Addiction: Nicotine creates both a physical and psychological addiction, often resulting in intense and persistent craving. Withdrawal can be eased via nicotine replacement devices or the medical use of antidepressant drugs.
Trends: Under terms of a recent national court settlement, the tobacco industry is barred from targeting promotions at young people and must even develop anti-tobacco campaigns to reduce use. But they've sure got their work cut out for them. At last count, 45.9 million American adults were still puffing away and another 8.6 million were using smokeless tobacco products.
Demographics: Although use among young people had been on the upswing in the 1990's, national surveys have reflected a steady drop in smoking in recent years. In fact, previous-month use among high-school seniors has fallen by more than a third in the past decade -- sliding from 31.4 percent in 2000 to 19.2 percent in 2010.
