Immune to Meth

[jrock0069]

I started using meth when I was 11. I didn't become a tweeker until I was 14. After a few years locked up I started using again when I was 17. After about 4 months of using, I no longer was effected by it like I used to be. I would spend hours smoking it with my friends and eat right afterwards. I could just fall asleep at any time and I didn't have to force myself. I stopped finding thing to tweek out on and eventually became bored of the drug. I stopped using it until about a month ago(I'm now 20) A coworker of mine had some with him and offered me some, I had a few hit's and didn't feel a thing. I was wondering if this has happened to anybody else?
