I do not smoke Tobacco and is interested in what effects a Tobacco smoker gets from having a smoke. I tried several times many years ago as a teenager and remembers a headrush with mild nausea, but their must be more to it than that for it to be so popular. Erowid states effects classification as Stimulant, yet some claim it to be relaxing. How would smokers describe the effects of having a smoke? Does it keep you awake, help you sleep, calm you, motivate you or give you a euphoria?
