Re: 1,3-dimethylamylamine SWIM actually gets a nice rush when insufflated at a low dose (5-10mg) but not for very long and not particularly memorable - oral dose works as an adjunct to coffee for productivity enhancement, but not really as a recreational stimulant (~30mg). I do not know about vaporization or plugging. Insufflation is painful but the burn only lasts a minute or so - not like snorting a 2CX or other caustic powders (OUCH!). However, I do not advocate insufflation since it could be dangerous. Don't be stupid like SWIM ... I have not had the drowsy after-effects reported by Nag's primate, though I get that somewhat randomly from stimulants in general. I have also not noticed any particular mood changes or hangover after use so far. However, overall I agree with Nag's primate - mostly a dud but good as an addition to SWIM's morning coffee or a booster when tired from long hours awake. Hopefully it at least motivated bongo to groom some more fleas out of his fur !
