Why can't I sleep after I smoke cigs?
I know it's the nicotine, but does nicotine work as a stimulate or what's going on?
Cigarettes have nicotine which a stimulant. Stimulants elevate your blood pressure depriving you of sleep. Once the effects of the nicotine wear off, you will be able to sleep. Take the cigarette at least 2 hours before sleep.
Its a stimulate. Elevates the blood pressure.
