I've been smoking meth for about 4 months and earlier today a few hours after smoking I noticed a strange black spot in the back of my mouth where my wisdom teeth would be. It's not a flat spot, I can move it like a scab, however it is not hard like a scab would be. I have no idea what it is or if it was caused by smoking meth. I looked online and couldn't find anything similar, so I turn to you. I took a picture..you can't see it that well but I figure it'd be easier to show than it would be to explain.
