Question

What drug can cause rotten teeth and mouth cancer

Answer 1

Methaphetamine can also cause tooth decay and mouth cancer

Answer 2

So when you smoke crack or put powdered cocaine in your mouth, the acids coat your teeth and can break down their protective enamel. This can cause gum disease and tooth decay. If you rub it on your gums, it can cause mouth sores. Smoke from pot is a carcinogen and can cause mouth cancer.
