I am just wondering, because I never have. I have had times that were a little unpleasant for a little while physically, but never anything emotionally or mentally unpleasant. I have had unpleasant passages on LSD, STP, and even a little bit on shrooms, but never on peyote (which is the main form I used to have access to mescaline back when I used to trip, many decades ago.

yes, once when I smoked cannabis with the cactus..and another time when I started to have a panic attack and nearly passed out from low blood sugar/pressue in a parking lot-that time I had sort of fasted. Never tried to eat cactus without having some fruit for breakfast first again, and I never smoked cannabis with cactus again.

When I have had positive experiences with Cactus, they have been MARVELOUS.

When I have had dark journeys, they have been very dark indeed.

Usually the times I had dark journeys I had eaten a big lunch the day of (stupid idea in retrospect) or somehow the set and setting werent perfect.

The dark vibe is this kind of vunerability that lasted long into the next day, and this sense of fear. I also saw and felt dark entities around me and in my house (aliens).

I have also had dark audio hallucionations duringt hese dark journeys which have scared the bejeesus out of me. It sounded like demons whispering into my ear a few times.

Most of my journeys have been extrememly positive, but when it gets dark it can get dark.

I am much more cautious about how I approach cactus today but have a great respect and love for it deep down.

Mescaline is such a friendly substance, I have never had a bad time and feel happy pretty much the entire experience. Have yet to find anything unlikeable about el mescalito even at high doses.

While my experience is also all positive with Mescaline, I can certainly see how it would cause a person to feel vulnerable. I remember how I felt one time when I was in the peak of a peyote trip, and I was barely seeing anything that didn't swirl into "rolling logs" or swastikas, and my girlfriends nipples were shooting out sparks in spirals, one boob clockwise the other one the other way, and like thousands of little mishapen beastys are just shooting up out of no where, and she decides she is bored because she threw up right away, and didn't get off, so she wants to go out to a bar. And she is like insisting, she's not gonna stick around until I am straight enough to make love and pay her any attention. And we are somewhere where she doesn't really know the culture. So it's like , fine, go, I have to stay here, because I can't deal with that kind of stuff, basically because I was so high that I felt vulnerable, which is only natural. If we were living in nature, you wouldn't trip unless you had some security, a little pause were you didn't have to struggle. A good harvest, the vikings haven't been heard from for a few months, a feast day alone or with friends, -- drop!

When I think of it, peyote has given me some of my most visual in a mythical, sense, the most fantastic hallucinations that would be not just flowing detail and patterns, but people and animals and gods and demons; stuff that should scare you, but there is always this just calm, like none of it can reach me, strong observer parallax.

I remember the first time I took peyote, It was magical. I had like two dollars left and I decided to go and buy a pack of Russian cigarettes, for no good reason at all. I was in Tucson, about early seveties, and I pick up this hitch-hicker, a young well dressed Mexican kid. I ask him were he's going, and he asks me where I am going. I tell him, and he wants to come along.
Anyhow, I was broke until the next day, so he offered to buy me dinner after we finished shooting pool. We went to a Polynesian place and he got his own private room for us, and we feasted. Then we went to his friend the brujo who lived by the university, and he had these huge fresh buttons. Like three times bigger than I ever saw again. He pulls them out of the fridge and they both watch me with great interest as I eat some.

I didn't know they were supposed to taste so bad, and they didn't taste bad to me. But evidently these guys were waiting to laugh at me when I spit it out. So their asking me like, "Tastes Ok huh?" And I am chomping away on his fresh peyote saying, "NOt bad." So they thought I was alright because Mescaleto obviously liked me a lot more than them, because they were pretty affected by the taste. We partied until dawn, at which point I fell asleep in my car outside a bar, and never saw either of them again.

Panic attack -- I think most of the time that I didn't properly enjoy various recreational molecules it was from panic. Like a snowballing of stupidity on my part. Something would startle me or something, then my heart would start to pound, but I would notice it a lot more, and this would scare me, because I would think maybe I was gonna have a heart attack, and it would just build up. I would say they were all similar to that in some respect, except for one, when I took way too much STP because I thought it came on like acid and nothing was happening, so I took some more, this was a big mistake. Later I found out that people were bumming out on it, even if they didn't take four or five times the heroic dose. The other big mistake I made was using LSD and Levodromiran at the same time. Made sense to me, I loved acid and I loved synthetic heroin, why not make it really good and do them together. It wasn't horrible, but it was like an internal struggle between the two drugs, and I didn't derive any pleasure from either of them just four hours of pacing instead of seeing Santana and Crosby Stills, Nash and Young. Bummer, well not a bummer, but it was a bummer to miss the show.
