I recently started vaping but now my legs are turning black? Like, not dark brown but completely black like my hair?

Vaping isn't a good idea. It's got nothing to do with your legs turning black, but vaping is totally pointless.

Are you sure it's correlated, it might be due to diet change besides vaping, but if it continues to worry you, I'd definitely agree that a doctor would be the best way to make sure everything is alright.

You're legs?? Dude, you need a doctor.

Interesting that you are able to see the inside of your lungs.

I'd go see a Dr and stop vaping
