my back from Amsterdam and he has a little bottle of acasia mixture, which appeared on one smartshop on the last day of his stay. He gave it a try and it did give him a bit trippy feeling and everything looked funny but not anything like full-blown DMT experience. He thinks it isn't concentrated enough at all to get the full effects. You'd have to smoke it several grams, right? He propably should do the extraction if he's to buy more of those someday.
