How long ago was this?
can deteriorate if it's exposed to light, but that didn't happen as it was wrapped in foil.
The heat from your butt and the car may have degraded it, but if it was only for an hour, barely anything would have happened to the acid.
In my opinion, I think the acid is just weak. So yes, you may have been ripped off. Lots of LSD these days is very weak and it could take two or three to even get minor changes. If the three didn't do anything after a good seven hours or so (wait to make sure it's not some research chemical
that takes a while to kick in), I'd wait at least a week for tolerance to go down and then take the other five all at once on an empty stomach. If you smoke pot, perhaps a small amount of weed
would help it along.
Usually, I can get plenty of visuals off a single tab, but I get visuals very easily (even from marijuana
, and even when I'm sober sometimes). Good luck!
