Withdrawal occurs as a result of dependence, when the body becomes used to having the drug in the system. Being without nicotine for too long can cause a regular user to experience irritability, craving, depression, anxiety, cognitive and attention deficits, sleep disturbances, and increased appetite. These withdrawal symptoms may begin within a few hours after the last cigarette, quickly driving people back to tobacco use.

When a person quits smoking, withdrawal symptoms peak within the first few days of the last cigarette smoked and usually subside within a few weeks. In addition to its pleasurable effects, nicotine also temporarily boosts aspects of cognition, such as the ability to sustain attention and hold information in memory.

However, long-term smoking is associated with cognitive decline and risk of Alzheimer's Disease, suggesting that short-term nicotine-related enhancement does not outweigh long-term consequences for cognitive functioning. In addition to the drug's impact on multiple neurotransmitters and their receptors, 30 many behavioral factors can affect the severity of withdrawal symptoms.

For many people who smoke, the feel, smell, and sight of a cigarette and the ritual of obtaining, handling, lighting, and smoking the cigarette are all associated with the pleasurable effects of smoking and can make withdrawal or craving worse. Nicotine replacement therapies such as gum, patches, and inhalers, and other medications approved for the treatment of nicotine addiction may help alleviate the physiological aspects of withdrawal 37—39 see " What are treatments for tobacco dependence?

Behavioral therapies can help smokers identify environmental triggers of craving so they can use strategies to avoid these triggers and manage the feelings that arise when triggers cannot be.

Nicotine can spell trouble at any life stage, but it is particularly dangerous before the brain is fully developed, which happens around age The reward system, called the mesolimbic dopamine system, is one of the more primitive parts of the brain.

It developed as a positive reinforcement for behavior we need to survive, like eating. Because the mechanism is so engrained in the brain, it is especially hard to resist. When a teen inhales vapor laced with nicotine, the drug is quickly absorbed through the blood vessels lining the lungs.

It reaches the brain in about 10 seconds. There, nicotine particles fit lock-and-key into a type of acetylcholine receptor located on neurons nerve cells throughout the brain. This neurotransmitter is used to activate muscles in our body.

The reason nicotine fits into a receptor meant for acetylcholine is because the two have very similar shapes, biochemically speaking, Addy explains. But nicotine, unlike other drugs such as alcohol, quickly leaves the body once it is broken down by the liver. When an addicted teen tries to quit nicotine, the problem of cravings is of course tied to the drug that causes the dopamine rush, Addy says.

This means that simply seeing a person you vape with, or visiting a school restroom—where teens say they vape during the school day—can unleash intense cravings.
