General Discussion

Kratom is a natural product. It is a weird drug that acts on a lot of different receptors, but to my knowledge does not have THC binding like effects.

There are synthetic cannabinoids out there, I want to say delta 7 or some such.

Edit -- Kratom has some interesting binding. Seems to, at low doses, exert effects on dopamine and serotonin systems, and at high doses it hits opioid receptors. Since it hits kappa and not just mu opioid receptors, I'd wager it isn't as fun as the usual pain killer stuff.
