i do however find dissociatives make my voice sound funny lol to me anyway. And i always feel so insanely fucked up, there's no way you could not tell. I don't know why but amps, benzos and opiates are dead give aways for my family, i don't know how they figure it out. Probably after i end up accidentally falling several times or for being 'too' happy.
@toz: do you find you can pretty much do any normal task while high? I used to go to lectures (poetry, english, philosophy of course) while on 2c-e, 5-meo-mipt, DXM, MDMA or whatever psych i had around and no one would notice. I often have to tell my gf i'm actually on a drug, otherwise she just has no idea. I find it strange that people get so paranoid about someone figuring out if they are high or not, even on high doses of anything but dissociatives, i can keep my shit together enough to sound/act like a normal human being. And for the most part, the vast majority of people i meet wherever in my area at least smoke weed if not coke/opiates/benzos.
