yea they fuck u up pretty good so maybe u were just trippin a bit more then normal, but their really effective, i remember the first time i tried it i inhaled it so fast as i was pushing it down that some water rose up and went into my mouth and once i finally spat it all out i realised i had the smoke in me the whole time, i fucked me up so bad that i just exhaled an sat there looking at starts trippin for like 10 min
