Sorry if this is off-topic, but after the first time I had ever rolled, as I was coming down, I had a SINGLE hit of a legal smoking blend called "Space". I went from feeling nearly sober to having fully-encompassing, 3D geometric patterns, swirling and twisting about in my field of vision, that began transforming themselves into the singularity that was before the big bang. Meticulously, I re-lived the entire creation of the universe, from the forming of stars, planets from their gases, and moons from the leftover waste to unicellular bacteria multiply and become multicellular organisms, beginning the first steps of biological evolution. Then, after I realised I had arrived at the present, faces began to appear in my field of vision in a dream-like sequence of events where I would see my friend, then his sister and my parents repeatedly. I saw their faces and knew them as their relation to me, but I could not recall any of their names; none of the associations I made or had were communicated through internal monologue in any type of language. I also heard my friend ask the same three questions over and over every few seconds, as if he were on playback. Soon after this stage in the trip I regained mobility (I had apparently fallen to the floor) and stood up. Eventually I arrived to my friend's bedroom, where I slowly regained the ability to think and process what the hell had just happened. Odd, to say the least, especially since MDMA isn't a true psychedelic. I suppose it could have been cut with something else, however I had no symptoms aside from the steretypical effects of MDMA intoxication.
I have and probably always will smoke during any experience, especially a psychedelic one.
