Q: Is there any method (other than ingestion) to tell whether a substance is LSD?
A: The only way to definitively identify LSD is to do laboratory GC/MS testing of the material. But one field test is based on the fact that LSD glows under UV light (blacklight). Obviously other things glow under blacklight as well, so just the fact that it glows doesn't mean it's LSD, but if it doesn't glow, LSD can generally be ruled out. The glow is apparent in crystal form, liquid form, or liquid dropped onto other material such as blotter or sugar cubes.
