The one close to confirmed case of LSD overdose that I have heard of, and this is still only net hearsay so take it with at least 500ug of salt. A man intravenously injected roughly 350mgs of LSD which was originally in powder form. This is a fucking HUGE overdose, far and away beyond what could possibly be contained in a fucking SHEET of blotters.
Unfortunately as with other drugs, people assume that there is a 'standard' trip, totally failing to take into account that especially with potent hallucinogens such as LSD that what you get out consists of the sum of what you put in, that is, the strength of the drug, but also (and this is what people forget) your mindset, attitudes, baggage and where and when you take it. This can mean that take two of the same blotters on two different days, maybe one day you have a revelationary and enlightening experience in which the universe opens up to you, revealing its secrets in moments of such piercing beauty you want to cry with joy. And on another day, it feels like the pits of eternal doom have snatched you from your mothers womb and pulled your darkest secrets and shames out of your own disemboweled body and forced you to endure fear and pain beyond your darkest nightmares.
Same drug, different thoughts. Look what happens.
I very much doubt that this was a different drug other than acid, as often that's the easiest excuse people can think of to attribute to why this particular experience was so different to what they are used to.
I've had terrible trips and I've had great trips, but you always have to remember and keep in mind that the drug WILL work its way out of your system, and to quote a piece of graffiti I saw the other day "These bad days will end". Just got to float and wait, though of course sometimes it feels like its never going to end, and when you've had a particularly confronting trip it DOES feel like your brain is burned. But just like when you bash your toe on a rock, the bruises fade and eventually you feel more or less the same. Of course, not exactly the same, which is, why we take acid, or why I do...
I'm sure I've repeated what the people before me have said, and its all old news, but hey, I thought maybe I could put in a little different light.
