Did enough butane and Lynx/other aerosol, as a kid. It's actually not that bad, when you've not tried real drugs. Makes you dizzy and giggly - it makes you completely pass out and dream insanely (and possibly nearly die), if you insist on emptying half a can of butane, after a load of booze. That was an often occurrence. It felt as though the high was coming from something seriously dangerous, however, which it obviously was. Starving your brain of oxygen for a high is definitely the way to fuck up. I can actually remember the exact feeling, although it was about 11 years ago, the last time. Oddly nice, but certainly damaging/fatal. I'm lucky to be alive, and there's a million other times that I think that about.
Salvia. I'd do it again, but it would have to be planned down to the last detail. Not going to describe it again. Fucking terrifying, but clearly very benign, so it might be worth another go. I've had a drink, so I'll probably change my mind tomorrow.
Stupid/intolerant people, as someone else said. People who have no idea about drugs, yet they say they hate drug users. Dangerous people, really. Inciting hatred, over something they have no understanding of. At least learn about something, before you become an expert. If you learn about it, and still don't agree, then go ahead. The fact is, when most people learn about drug use, they've actually dropped an E, or whatever and never look back. Stupidity scares me, because these morons are the people I have to inhabit the same planet as. I'm not friends with many un-intelligent people, as I get really angry and anal about people that don't know what they're talking about. That sounds like the rant of someone that is on cocaine, but I'm not. I don't view many (if any) Bluelight users to be stupid, by the way. You wouldn't be on here, if you were.
Needles. If I'm holding one, that's fine. If you're holding one, you better be a nurse, or a fairly good distance away from me. Despite having piercings, I couldn't have one now. I do not like them, unless I'm using them for something.
RCs don't scare me, but I'd be very unlikely to buy any, at all. I've not bought RCs many times, and now would be the height of me not wanting to try whatever is on offer. Fuck them. I'll carry on with the 'old RCs' (2C-B, etc.). Not that you could call 2C-B a research chemical, any more - same as aMT. How is aMT a research chemical? It's 50 years old. I've got some MPA, but I'm too scared to take it in above 10mg circumstances, in case of it sending my blood pressure through the roof (something some people reported, at low doses). It seemed to disappear, so I assume it's total shit, anyway.
Spiders. Self explanatory. If someone says 'why are you scared of spiders, you faggot?!', I'd tell them to close their eyes and quietly sneak up on them with an axe, and say 'surprise, you cunt!'. That's how it feels. It's irrational bollocks, so I can probably blame my mum.
Dying is something I'm getting less and less scared about, but more emotional about it happening. It can't happen, because I've got a son who needs me for as long a time as possible. He's the reason I'm alive now. He's the reason I'll continue to bore the world with my shit. He'd fucking love that I'm using him as an excuse to be a dick, but must maintain a proper parental image.
Religion. Don't need to say anything else on that.
Some other stuff... Good thread idea. Although, change it to 'wariness', please.
