DXM, Kratom, Kava Kava, Hawaiian Baby Woodrose seeds, Nitrous, Benadryl (I don't recommend doing this one.), Phenibut. Idk. I'm sure there's more I can't think of off the top of my head. Most research chemicals are in a gray area legal status. I think some, like the RC benzos should be "legal" since they're Class IV drugs and not covered by the analogue act.
