A week or so ago or so there was a great drug discussion thread but it sadly died before I could really check it out.
I was mainly interested in the discussion, so I'll try to dump a shorty.
I really DO hope it won't be modded off, so keep the discussion legal. No sourcing etc.
In general, as someone who has dabbed in many substances, the thought of a drug that makes you incredibly, incredibly horny really gets my hard, no matter the route of administration, but I prefer to keep it in-fantasy; monstergirl venoms, tentacles with aphrodisiac fluids, alraunes, futanari cum, or just two normal people.
I mainly looked in sadpanda and literotica the most, but any contribution is welcome
