Have tried most , exept heroin and crack and shit like that, mostly amfetamines and xtc though during my younger years, say from 19 to 23. Weekends and events with my buddy´s no harm no foul, all got out of it and none suffered because of it, that is of my closer friends. Have seen some aquantances from that time didn´t come out that good, still fighting the habbit , atleast a few and mostly damaged , there is nothing I can talk to theese guys today (conversation), there is definite damage. And I have seen far worse cases than that, the father of my spouse runs a institute for drug addicts that want to get clean and theese are often people in their 40 and 50´s that have used since they were teenagers. The most damaged ones that never can become like normal people to some extent are the ones on heroine and hashish/weed, also the cokeheads are pretty screwed up even though clean for 5 years, as many come to visit and come to meetings and stuff, but the hashheads, which is really underrated as hazardous as it sneeks up on you after years of use, I´m telling you theese people become clean but they dont recover, serious phsycotic disturbances and hallucinations years after use was suspended, most end up in suicide. There was this one guy in his 50's that even years since his abuse while fighting the phsycological problems he poked one of his eyes out with a spoon or a fork, no not both at the same time, and you´d think he learned the value of sight after his first endavour, but a year later he poked the other one out in similar ways. You should see his picture, what a human misery, a stain of human kind, this from years of abuse of hashish mostly but ofcourse some other shit problably too. Most of the people there I have met that have come out reasonnably ok after f.ex. 20 yrs of drug abuse are the ones using stimulants like amphetamine, then I mean reasonnably, not like nothing took place. So beware it could sneek up on you, 40yrs old still using, none of your old buddy´s left, there comes a time when one has to deceide after a few years of having a lot of fun and goofing around, IS THIS WHAT I WANT TO DO , IS THAT WHAT I WANT TO RISK BECOMING. There are other things in life that can be very uplifting. I wasn´t any angel nor am I telling you to do anything, couldn´t care less, I am out for my self and my family solely nowadays, think of your self first hand do what you think is best for you.
