hello i am a 14 year old male who recently after smoking them for a year just stopped smoking poppers (1 inch snip of cigarette topped with marijuana smoked out of a bong). B On my 3rd day of no smoking, I felt a dull pain in the center of my chest, since then i ve been experiencing this sharp pain regularly in my heart.
