Insomnia is one of the many disturbing side-effects of smoking. If you are already having problems trying to nod off, smoking will only make them worse. It is a fact that smoking and sleep problems go hand in hand. Cigarettes contain the stimulant nicotine, which can keep you awake and alert, interrupting sleep.
Nicotine is highly addictive. An average cigarette yields about 2 mg of absorbed nicotine, and in lesser doses of that order, the substance acts as a stimulant in mammals, while high amounts (50â100 mg) can be harmful. This stimulant effect is a contributing factor to the addictive properties of tobacco smoking. Nicotine's addictive nature includes psychoactive effects, drug-reinforced behavior, compulsive use, relapse after abstinence, physical dependence and tolerance.
