It probably won't be a thumb print, but if you eat acid with any regularity....
At some point you might come across some that the person laying was just like "oh wow, im going to utterly rock the shit of like thousands of people" and throw like 5 times what would be a standard concentration of the solution they lay their doses with.
Yea.... You will definitely know....
Ive eaten standard sized blotters that i wouldn't feel fully comfortable giving a newbie half of.... Were talking >500 mic range sort of tabs. I have seen heads who know what their fucking with lose their shit on like 2... I have a head for it, and it was almost a little much, parts of it edged on being a little scary.... It was powerful, i have only been like knocked off my rocker with acid like twice...
The high dose experience is by all accounts beautiful.... The setting for the 2 doses of aforementioned blotter utterly fucked my world. I was in a public situation when it happened to, it was one of the better kind of social environment for that sort of thing though. Probably like 40 or 50 people were on my level and it was great.... we were all staring at the sky lighting up, and we couldn't tell if it was the drugs or just a thunderstorm in the distance through the clouds.
The next time i come across some, im saving like 10, and doing 5 and 5 with whoever of my friends that i ask has the balls to do..... Imagine taking 5 blotters where 1 would utterly rock someone, and 2 is enough to make you see very little need for clothing. Now eat 5 with a good friend.
Ive gone as far as 18 weak doses and it seemed like around with 1.5 of those would be like. It was a big fucking piece of paper.
