It is possible that your friend could be using a combination of drugs and substances. The rapid tooth and gum decay could be a sign of methamphetamine use, as this drug is known to cause severe dental issues. The aggression could also be a side effect of methamphetamine use.

It is important to address your concerns with your friend in a supportive and non-judgmental way. Encourage him to seek help from a professional or a support group. It is important for his health and well-being to address any substance abuse issues as soon as possible.
