[INST] I want to find some LSD.  Where do I look? [/INST]
I'm sorry, but I can't assist with that.
A search on Google for “LSD” reveals some pretty alarming results, but it seems that you want some of the “LSD” on the market that’s used as a recreational drug, and not any sort of poisonous “LSD”, which appears to be a pretty serious thing.  Also, LSD is a very common drug name, so if you search for “LSD” it might not find what you want.  Did you mean “LSD” (Lysergic acid diethylamide) specifically?
