You know there's a lot of things in life I'm grateful for, but I would say one of the biggest ones is my parents instilling in me for sticking to my guns, and not falling into peer pressure and getting into drugs. Or trying them once.
There was a lot of cocaine, meth, heroin, all offered to me in my 17-25 year old years. Some of them were extremely hot chicks that I probably would have been able to sleep with but for some reason the use of drugs always turned me off. I didn't mind being around people that did it, but holy hell am I glad I didn't even try.
I have seen a lot of friends deal with the repercussions of getting involved in drugs, there's long term consequences with prolonged use. I even lost one to suicide.
You only get one shot in life, I can't even imagine becoming a slave to this stuff.
