me and a friend did some weed then went for a walk and found what looked to be a blackberry tree, we were like wtf a tree??? so we go online and sure enough there is such thing as a blackberry tree... so we pick like 1.5-2lbs of them and go wash then off we eat about .5-1lb each and we thought they tasted funny and just asummed that they were unripe... about 30mins-1hr after eating we start tripping, i mean like feeling funny(kinda like the feeling when you laugh for 5 mins strat), everything went really slow and we did what ever came first to our mind we coulnt rember what was goin on... this lasted for about 2 hrs.. we were freaking out and somehow figured out that they were mulberrys and that you could trip on them(1 experence on erowid)...has anyone else tryed or accedently done this? for the people saying you cant trip...I have found some info over the internet that seems to sugust that the unripe berries can make you trip trust me unless the weed had something random in it(dbout it because i had smoked some of it the day b4)
