Amyl Nitrate. LOL! I guess it is cheating to say that because it is kind of woosey as far as drugs go. But I've had my head pinned down with a bottle jammed under my nose where I sucked up so much of that shit that I screaming the fucking house down. I'm surprised the neighbours didn't call the cops! Seriously. : ) It was awesome!
I tend to avoid hallucinogenics for the large part. I haven't had it in years, but don't mind a little bit of leaf and tip. My brain was always really sensitive to marijuana. In fact, years ago my pot smoking neighbours used to invite me over for entertainment so they had something to laugh at - half a cone and I was a giggling mess. Trouble is, anything too strong used to give me really bad trips which weren't fun, so I usually avoided it. Then, when my Mum turned 48 she got schitzophrenia - she was probably latent her whole life but the acute phase was brought on by smoking too much pot. With my sensitivity, I have no doubt that if I started smoking bud on a daily basis I would end up schitzophrenic and I don't want that. So where as I don't have a problem with other people smoking pot, I don't tend to do it much myself because it doesn't suit my chemical make-up. Hanging for a cookie though.
And about 15yrs ago I did a bit of speed for a couple of months. Fortunately I was only taking small amounts and I had witnessed a few friends get hooked to the point where they were living junkie lifestyles. But I was injecting it, and I remember waking up one morning and all I could think of was getting a hit and let me tell you, that realisation, that I was on the precipice of becoming a speed freak, was the biggest rush of all. My blood went cold! That day I went to my doctor and got some scripts for Duramine (legal tablet amphetamines for weight loss. And truck drivers like it) so I could get off the speed. I swallowed them like candy for a coupe of weeks and then weened myself to one a day and after a month I was free. Thank goodness!
Overall, I haven't taken much drugs in my lifetime, and don't really feel a need to. My mind is trippy enough without adding drugs! Would still be interested to snort cocaine off a bloke's cock though... Haven't tried that yet... And maybe opium, but I think that might be a hallucinogenic so maybe not a good idea.
