In the years i used to take acid, there was one type of blotter that i had twice (it was called 'sun' and had a picture of a sun with a dark blue backround spread over 4 hits) that very much had an LSA feel to it. This is one of the few times i doubted whether i had real LSD. they where very weak, basically but had that toxic feeling. They also gave me short blackouts.

There was a similar blotter with a picture of a purple budha on it, that also had LSA-like effects and made me feel cold (there where other, orange blotters with budha-pictures, that where quite nice though).
