Those friends are golden. I burned too many bridges before I got free of the grip of using various drugs almost daily. My teenage years were a blur. By the time I came up for air, I only had one real friend left. My circle of "friends" while I was using was pretty volatile; they came and went.

Eventually everyone using either breaks free or gets consumed by it. There are not a lot of long term happy users. I am speaking of drugs like meth or in my day MDA and "T" (PCP).

Reach out to your old friends. Remind yourself what's real and lasting.
