The amount of nicotine in most cigarettes rose an average of almost 10 percent from 1998 to 2004, with brands most popular with young people and minorities registering biggest increases and highest nicotine content, according to a new study.
Nicotine is highly addictive, and while no one has studied the effect of the increases on smokers, the higher levels theoretically could make new smokers more easily addicted and make it harder for established smokers to quit.
Smoking is a powerful addiction. Smokers often make multiple attempts to quit before they can successfully stop smoking. Increased nicotine yield may make it much harder to kick the habit.
