Are tobacco, nicotine, and vaping (e-cigarette) products addictive?
Yes. It is the nicotine in tobacco that is addictive. Each cigarette contains about 10 milligrams of nicotine. A person inhales only some of the smoke from a cigarette, and not all of each puff is absorbed in the lungs. The average person gets about 1 to 2 milligrams of nicotine from each cigarette.
Studies of widely used brands of smokeless tobacco showed that the amount of nicotine per gram of tobacco ranges from 4.4 milligrams to 25.0 milligrams. Holding an average-size dip in your mouth for 30 minutes gives you as much nicotine as smoking 3 cigarettes. A 2-can-a-week snuff dipper gets as much nicotine as a person who smokes 1½ packs a day.
Whether a person smokes tobacco products or uses smokeless tobacco, the amount of nicotine absorbed in the body is enough to make someone addicted. When this happens, the person continues to seek out the tobacco even though he or she understands the harm it causes. Nicotine addiction can cause:
- Tolerance: Over the course of a day, someone who uses tobacco products develops tolerance—more nicotine is required to produce the same initial effects. In fact, people who smoke often report that the first cigarette of the day is the strongest or the “best.”
- Withdrawal: When people quit using tobacco products, they usually experience uncomfortable withdrawal symptoms, which often drive them back to tobacco use. Nicotine withdrawal symptoms include:
- problems with thinking and paying attention
- sleep problems
- increased appetite
- craving, which may last 6 months or longer, and can be a major stumbling block to quitting
What about vaping (e-cigarettes)?
Vaping products, also called e-cigarettes, are fairly new products. They’ve only been around for about ten years, so researchers are in the early stage of studying how they affect your health.
How Vaping Products Work
Vaping products are designed to deliver nicotine without the other chemicals produced by burning tobacco leaves. Puffing on the mouthpiece of the cartridge activates a battery-powered inhalation device (called a vaporizer). The vaporizer heats the liquid inside the cartridge which contains nicotine, flavors, and other chemicals. The heated liquid turns into an aerosol (vapor) which the user inhales—referred to as “vaping.”
