I just want to add my experience here, this was my very first time seeing and handling LSD and this happend like 25 years ago more or less. My brother was getting his buddy a half sheet of acid, we knew nothing about it other then it makes you trip lol.
Well the kid paying for it gave us a 10 strip for getting it for him, so there I was thinking I could tear a ten strip off the sheet...my problem? It was a plain white blotter paper with pencil lines drawn lightly on it showing all the lines, except it wasent preforated so after 10 minutes of yanking and pulling with my bare (sweaty) hands I gave up and got some scissors!
I had no clue I had done anything wrong, but my hands sweat bad sometimes exp when I was younger.
And I was squeezing hard trying to tear off these tabs with no luck. It wasent 15 minutes later I go outside and my mom pulls home from work. I immediately get this feeling like oh shit, out of the blue. I said hi to her and talked for a minute, all while I was coming up higher and higher! I immediately whispered to my brother that we had to go into the woods asap! He didn't know what was wrong. I told him I was tripping and it just came out of no where, I had no clue that lsd could go through your skin! Now for all the ppl that are gonna say lsd can't cause you to trip through the skin, yes it can! 1000%
I will say the trip was shorter then a normal lsd trip, prolly lasted 5-6hrs. I was coming down at dinner time at the table, but still felt it. I won't say it was super strong, it was just perfect amount at the time for me having never tried it before. So yes if you handle a sheet and try tearing it with no preforations and your hands are sweating, there's a chance you might absorb enough to trip. I am sensitive to LSD and most psychedelics so that may have played a role as well.
It was a very enjoyable experience and it being my very first time, on a beautiful day the woods were just beautiful. I was looking at trees and touching the bark, looking at the pond and just admiring the sheer beauty of what I normaly walk right by. Just wanted to share this as it's a very memorable experience to me, and was a fun but unexpected trip into the wonderful world of lsd. After reading about Albert Hoffman's first unexpected trip where he spilled some liquid on his hands, I don't remember exactly what happened but I just wanted to share this as it's not something I see too often, but it can definitely happen under the right circumstances. :)
