Tobacco abuse

Also known as: Nicotine withdrawal
When people use tobacco products on a regular basis, their bodies develop a need for nicotine. If they don't get nicotine, they start having nicotine withdrawal symptoms.

Withdrawal symptoms and cravings for nicotine vary from person to person. They often depend on how much nicotine a person is used to getting. The more nicotine the body is used to, the more severe the symptoms are likely to be.
