its an amphetamine based phenethylamine (research chemical synthetically made in a lab [VERY DIRTY]) trip lasts about 30+ some odd hours.. go to erowid.org and go to chemicals.. makes ya trip though. just not my style. stick with lsd!
lol, DOB, I like this stuff, I've done it probably a dozen times. I like to keep my dose around 1-1.5 mg, otherwise it can be too intense and last too long. 30 hours? well, i don't think my DOB buzz ever lasted that long, but it wouldn't surprise me if the dose were heavy (>2 mg).
When I have house cleaning and organizing to do, DOB is my go-to chemical, very energizing and motivating...I always get A LOT done when I'm on DOB
As for "trippy" strains, Nebula is def a good choice, and Kali Mist is a classic sativa that's supposed to be trippy (haven't grown this one yet). Some other strains that [supposedly] can be "trippy" are Chocolope (DNA genetics), Ice Cream (Paradise) and Belladonna (Paradise).
The trippiest weed I ever smoked BY FAR was some bud that was dusted with PCP. I was in college then (twenty-something years ago). Man, what a night...I'll never forget it. I (probably) wouldn't ever do it again, but I'm glad I did, it was quite an experience, I can still recall some of the most vivid hallucinations I had that night, lol, quite magical at times (and terrifying at others).
