^ Can you show a study that shows its no more effective than placebo effect?
I didn't know 5-HTP could be used to potentiate the cannabis high seeing as 5-HTP works on serotonin and from the reading I've done THC mimicks anandamide to release dopamine into the synapse. So I guess I'm having trouble seeing where the two relate and potentiate.
^ It doesn't potentiate it. Weed actually decreases activity of serotonin. 5-HTP just tweeks the high so it's different. It increases some positive effects like pain relief and euphoria while reducing some positive and negative effects like racing thoughts or munchies.
