Drug info - crappy "acid": Weak LSD or something else?

[polloloco001]

the other day swim's friend bought some "acid" and ate it with swim.
swim had 2 tabs. after about an hour swim felt euphoria and extreme
happiness kind of like ecstasy. there were barely any visuals and his
thought process was more like non existant than trippy. this lasted for
about 2 hours. then it was over. swims fiend felt nothing from his
first 1 1/2 tabs so he took 2 more when swim began to feel it and he
still didn't. he never felt shit. i know it wasnt just paper becuase
swim felt soemthing. </span>does this sound like any kind of research chemical that could be put on blotter? or maybe just really weak lsd?
