Morphology

blotter = blot (opaque) = blot + er

The word is historically related to something that blots or absorbs liquid, but the sense 'single LSD dose on blotting paper' is a specialized metonymic extension not inferable from the morphemes alone.

Etymology

Blotter for a small square with LSD comes from blotting paper, because tiny drops of the drug are put on paper that 'soaks up' the liquid, and each small soaked square is therefore called a blotter.
