So me and my friend have been living inside the same house for about a month now. We are short on money and usually only one of us has a vape at one time so we always share. He usually borrows my vape for a little bit and brings it back but recently he’s been taking it for at least an hour at a time. I thought nothing of it until one day he handed it back to me and it had an odd taste. I thought it might be a problem with the vape but it got worse and didn’t taste burnt so I popped it open and there was a thick layer of slimy cloudy liquid. I immediately was in denial that it was his ♥♥♥ and tried to think of every other possibility but it was definitely ♥♥♥. This was yesterday and I already got myself a new vape but I still haven’t confronted him about it. What was he even trying to do? I’m just so confused and don’t know how to handle this.
