not for the inexperienced drug user
really intense!

2cb is a crazy hallucinagen
the body high feels like a really magnified verion of E
With the visuals of acid
i was seeing everything in square pixels
and all the colors kept changing
everything had a crazy texture to feel
i took 1 capsule and tripped balls for a good 6 hrs
it was powder in the capsule so it was pretty pure
the comedown isnt too bad, just smoke bud
i took 2cb and had 4 shots of everclear and 2 shots of jd
and i was peaking for 8 hrs
