Slang used for acid (LSD) on a blotter strip. The blotter itself usually comes on a sheet of 100 strips or more. The producer puts at least one drop per blotter. Put the blotter on your tongue and let it dissolve, DON'T SWALLOW. Wait til the paper has almost completely dissolved in order to get the full effect.
