Actually my tolerance to drugs in general is meh at best, unlike alcohol which is have a rather ridiculous tolerance for.
There's a few other potential factors involved that I wont go into great detail in for personal reasons (even I keep some things private), but there was a large amount of medication involved which may have had an effect.
(among it were sleeping pills and a verity of anti-depressants that were switched regularly due to adverse reactions)
Kinda funny the shit doctors were willing to shovel down someone's throat to fix a problem back then; thankfully not something they do now due to better regulations.
It could be that it eventually came down to other things, like after a while it was more placebo effect than anything.
Another likely outcome would be bad gear + placebo for a few days, then back to working gear, which when we're talking about a young teen is possible.
There's a verity of possibilities, and I'm sure it'd easily pass the post size cap listing them all lol.
To address the psychological state... That wasn't good in the first place, and didn't improve until I was eventually booted out by the parents a few months after I hit 18. Take from that what you will.
I do have pretty bad anxiety issues these days but that could be attributed to many things. Never had any schizophrenic problems, and aside from typical teen "I'm gonna get caught" shit, paranoia wasn't really a factor.
The dark web bit made me laugh a bit, the UK barely had working internet in general until the mid->late 90s, it was pretty much just corporate sites back then.
(yes we did have internet access before then, but it was borderline pointless to have, so we'd direct dial BBS' instead)
Everything was via your friendly local dealers where drugs were concerned.
And of course the pricing was very different, even maintaining a smoking habit was rather easy for teens with 20 cigs being around £2. Same applied to most drugs, it can be pretty shocking to see the price on most these days. Seems weed is the only one that hasn't really changed much.
I honestly couldn't tell you specifically how much was involved in dosages, unlike now people didn't bother with knowing exactly how much of something was in what they took. Hell, we didn't even know numbers for things like that existed - info exactly freely available, especially in a relatively cut off area. (west cost of Cumbria for reference)
At the time we were supplied with what was locally known as "acid tabs", or as people call them now - blotters. £5 landed you a sheet around the size of 2 business cards, each tab being roughly the size of a pinkie fingernail. As to what dose that worked out at each - who knows? They were easy to stash & did the job, about all that mattered.
As stated in my previous post keep in mind that I do fall into the born with a silver spoon category, so cost simply wasn't an issue. Poor little rich kid eh?
