Cannabis is something that does not make you trip or hallucinate with your eyes, hence that is why it is called a recreational drug. I have smoked some of the best weed and hash in the world and I never tripped, however to the point of saying I did trip, it was just more clear revelations coming to my mind that I enjoy. Thats why I smoke it! If you want to "trip", either use salvia divinorum or mushrooms as they are the most natural ones. Treat it with respect and have an open and clear mind, as they will reveal yourself to you. Always keep it natural and stay away from man made drugs like coke and alcohol.
