So I smoked marijuana a few times before and each time I smoked, I would get this very warm, tingling sensation though out my entire torso. This feeling isn't at all unpleasant, but rather it feels good and comforting. Although I first experienced this when I was high. I have also felt this sensation when I'm not high. This sensation that I feel can go on for at least a month. The feeling isn't there constantly, but rather it happens in random intervals, coming and going. I was just curious to what this could be. So if you would please give me your thoughts. P.S. I am a 17 year old caucasian male, and have no health problems if that helps.
