Think before you use drugs is an easy thing for me to say now. I used to use drugs regularly for about 4 years. I started out smoking marijuana and ended up smoking crack and sniffing heroin and crystal meth. My story isn't a story about how I brought my self down, how I became homeless or how I destroyed my brain. I did at one point I think have a small stroke when speed balling crystal meth and special K. I have managed to recover my brain function and I managed to go on with my life in a somewhat normal way.
