I thought DMSO was icky and i didn't even put it in my mouth, i just let it absorb through my hand. You start to taste it in your mouth, you feel like your breath stinks, and it did make me feel kinda weird. I dunno, is it common practice to swallow DMSO? Would you run the risk of absorbing some not so nice stuff using DMSO, since it doesn't really screen out everything besides psychedelic drugs?
