I've had CEV's after smoking weed. I saw a vague image of Jesus' face staring at me, and it was slowly getting further away and fading. It had a reddish hue to it. It was very cool, haha.

Also, if you think about it, frame vision from cannabis is an OEV. I've had that many times. I've also been so high that I have seen people's faces as distorted. Well, it wasn't really distortion as much as it was that I couldn't understand how their faces looked. None of this stuff was laced, it was just straight maryjane . Cannabis can be psychedelic, given the right conditions and strains. I love it!
