Yea the trick is to snort it - the times I've smoked it, even in small amounts, it just dissolves my functional state of mind way too fast...
When it's snorted it comes on more like a fast mushroom trip...
In any case snorting large enough amounts for the whole ego death/one with the universe effect would render one totally unable to handle walking around, let alone driving...
I'm glad I had that period where I had nothing else really to use, because once the RC boom came and we had all the 2C's and the other stuff, I had no desire to be using 5-meo out in public much anymore... Before the RC boom though I had to make do and had the chance to try some things that I'd have never bothered with otherwise...
