Lately I smoke, but over time I feel strange especially in the heart. Sometimes it hurts on the left but only a few seconds. My friend suggested stop smoking and told me to use a vapor.
I've been googling about the effects of vapor to body, but the answer is less satisfactory.
How do you think, preferably a cigarette or a vapor?
Vapor things look very harmless, or they're explained as harmless, but they're very dangerous as well. You gotta try quit.
