Its a really hard drug
Ive taken speed in a needle for 17 years,im 47,sometimes full on for months,your life will turn to shit,sometimes once a month,thats more fun,its awesome for a big hit,some porn and great sex with your lady for 12 to 24 hrs ,its a great way to have sometime out from life.With speed you need to have an outlet for the intensity and we find sex is the best.You pay a huge price for the fun,as the next few days + suck,Hey if your going to play look after your body,make up for the shit you put in it,if it suits you play, if it doesnt dont,its addiction creeps on you,if you cant exercise some control with it,leave it alone,enjoy

Another amazing drug to be on while having sex. Much better then being on extasy but has about the same effects. Sex is amazing, but having sex while your on speed is even more AMAZING!!!
