Everything in the 90's that was available, except for heroin - I'll never do that, I've ingested, smoked and snorted. Fear of injections helps to ward off the more serious stuff, luckily. I actually saw heroin, at a friends place. I looked at it, then went to his sink and flushed it down the sewer. I'd do the same all over again when being faced with someone in my circle of friends using it.
My main substance was marijuana. In fact, if I hadn't stopped smoking altogether six years ago, I might still have been doing it today. Whenever I smell the scent of a freshly dried bud in my vicinity I admit to having to stop myself from not rolling one and lighting up, but I can restrain myself. I do miss it sometimes...
There's a really funny back story about the first - and last - time I ever did coke involving a rawk band of which Mr. E. is a fan, but as a whole, coke didn't do it for me. After being awake for most of the day and night (which was why I took it in the first place, as I suffered from sleep deprivation by way of partying too long the night before), the end of the night and of the coke 'high' felt like being hit over the head with a ten ton hammer, so much even, I couldn't stand up straight. Not my kind of thing.
A couple of weeks later, I tried speed and the end result was being terribly ill for two days straight and because of that, not enjoying a killer Pantera gig, because I was too busy feeling sick instead of enjoying the gig. Speed is bad news and for the life of me, I can't understand why so many musicians have a craving for it. This one certainly doesn't...
LSD was good to me, even though the events going on at the time I took it (four times in all) were strange enough by themselves. Ever tried to watch 'Kindergarten Cop' while on LSD? That certainly was a hell of a trip. I kept freaking out about once scene I found especially stupid and thus a perfect example of the stupidity of the whole scenario. Yes, those were good times ('t was the time before, or during, or after xmas; I'm not sure

). Another time was a couple of months later, while watching a game show called 'De Droomfabriek' (The Dream Factory). Since it's a great party story - much like that coke back story I alluded to - I'll refrain from talking about it here and keep it for when I'll meet up with some of you again one fine day.
XTC just made me feel horny and awake when I wanted to sleep and there was no one around to alleviate the hornyness. It also had the same effect as ingesting amphetamine : like having soda water bubbling inbetween your skin and your muscles. I don't like that feeling, even though others may...
Let's see, what else? Ah yes, psilocibine mushrooms. The home variety, freshly plucked and dried by either myself or my druggie friends, never gave me a bad trip. In fact, the best trips I've ever experienced were on these mushrooms. The so-called 'magic' (mexican) mushrooms, on the other hand, were not magical at all. I always ended up havign to fight my way out of a bad feeling I got with them and the last time I took them, it went horribly wrong. I ended up suffering from insomnia, anxiety attacks, subsequent depression, several bouts of epilepsy and I turned to alcohol to wash it all away for the next two years.
Let this be a warning that while I'm neither advocating nor condemning the use of substances, drugs are, as the late Jim Morrison said, a bet with your mind. And you can rest assured there will be a time the drugs win that bet whether you're careful or not...
