How long is the shelf life of cigarettes?

Generally speaking, the shelf life of cigarettes is about two years. The shelf life of cigarettes for more than two years is limited to the whole unopened cigarette.

In a cool, ventilated and dry environment, unpackaged cigarettes can be kept for one to two years. Wrap the cigarette with plastic wrap and put it in the refrigerator or professional tobacco protection box. In this environment, cigarettes will not expire for five to ten years.

The influence of tobacco on people

(1) Tobacco can cause nausea, dizziness and headache.

Nicotine diffuses to the whole body through lung mucosa and oral mucosa. After nicotine enters the brain, it can imitate the central neurotransmitter acetylcholine, activate related nerves and release more dopamine. With the strengthening of dopamine, serotonin and norepinephrine, people will be more awake and more focused, thus alleviating anxiety and enduring hunger.

(2) Smokers develop tolerance to nicotine.

Regular smoking can keep the nicotine content in the brain at a high level. Neuron receptors are less and less sensitive to nicotine, and their stimulating effect on dopamine release is also weakened. The original cigarette consumption can no longer satisfy the pleasure of smokers, and smokers are tolerant of nicotine.
