Acid doesn't take 20 years to metabolize. :)

https://americanaddictioncenters.org/lsd-abuse/how-long-system-body

"The half-life of LSD is 3.6 hours, which means it takes about that amount of time for half of the dose to be cleared from the bloodstream.4"

So, say you took a typical dose of 25μg to 150μg, 3.6 hours later you have 1/2 that... 12.5 to 75. Another 3.6 hours later, 6.25 to 37.5.

After even just a few days it would essentially be nothing. It's no longer detectable in hair past 90 days.

So if he is still trippin, you telling me this cat took 120g of acid?

[–] davidgro@lemmy.world 5 points 1 day ago* (last edited 1 day ago) (1 children)

... More like 2.5*10^728 grams. Which would be like taking the number of particles in the (observable*) universe, making a new universe for each one, then taking the number of particles in all those universes and making a universe for each one... 9 levels deep. That many grams.

(*Every time I say universe I mean observable)

Edit: Oops, I forgot it's 20 years, not just one. I think that's Multiply both the 728 and the 9 by 20.

Yeah, got better numbers from a better calculator:

1.8e14665 grams
That's 183 levels of universes of universes.

Ok, I dig it. What about perception of time. Got any info on that?

[–] StarvingMartist@sh.itjust.works 9 points 1 day ago (1 children)

I would suggest that's possibly a different issue and to see a medical professional

Never looked into the half life but first time it took like 6-7 hours to see the ceiling swirl nicely. I wouldn't assume many days lasting though. The wired framed mech I wanted to see out my 3rd story window at like 4am was beat though, especially when I made it walk back and forth.

But after many times, including after seeing the Teletubbies sun face randomly (actually not even the most awesome hallucination that trip), after 12 hours I was mostly sober.

Other time I recall was about 10 hours after first dropping went to a rave and got home,I saw some fun colours in the shower water, into infinity between the tiles, then yelled a Madeline cartoon cause they left their luggage 3 scenes before they checked in and had it next to them again..then went to bed and was all tired later cause my sleeping schedule was mixed up.

I wouldn't think it last longer than say 12 hours unless other factors are in play.

Edit forgot to say, most of my acid trips I saw no more than stucco ceiling swirling for a hallucination. So don't take these experiences as standard...well maybe the watching that Madeline episode that was stupid continuity but expected for a tv show made for kids.
