I didn't think it was coke that ruined your teeth, I thought it was usually meth that did that??
Don't believe the hype!
Really, how does "meth" ruin anyone's teeth?
It doesn't. You have an entire generation raised on it by now. I am sure their teeth are fine.
Now, being strung out on any drug, especially those whose fumes are inhaled and likely includes all sortsa adulterants ain't great.
And grinding your teeth for 5 years straight, probably ain't so great either. But hey, if you ever have to get to Chicago in a weekend, hard to a find a cheaper mode of transportation than walking while tweeking.
