I have seen some absolutely horrific incidents involving LSD and meth. One of them in particular involved my best friend at the time and my 30th birthdy party.
I set a rule for everybody. I said I didnt mind what drugs people wanted to use, the only one I was not having and would not tolerate was meth. Not due to any stigma as I use it myself but we had psychedelics planned and I had already witnessed horrible things happen to people who mixed them,
So what did my best friend decide to do. She smoked meth before she came to my house expecting me to be none the wiser.
Well about 6 of us took 2 250ug tabs, so 500ug all up on top of some other substances. I think maybe MDMA, cannabis, nitrous and ketamine.
Everything was absolutely fine and we were all having fun until she turned to me with the most deadpan look on her face and said "my name" "Im dying" in a very calm but unsettling tone. I said "What?" and she just kept repeating "Im dying".
Well I was obviously high as hell, confused and very concerned at this point as there was cocaine around and if she had taken meth then those 2 drugs have the potential to actually kill you and this girl was far from naive to LSD. So I began to panic and eventually I called an ambulance because I was unable to del with the situation in a way that I felt was appropriate.
Anyway she went to hospital and when she returned one of the first things out of her mouth was, lets have some MDMA. Well I totally lost it, I was fucking furious and ended up going to buy some heroin(which noone else used, was very confronting and most people had probably never been around it before and was not at all acceptable). Had a shot in front of everyone and laid my uncapped, used needle on the table in front of everyone as if to say "Fuck off now" and a gesture of pure anger, disappointment and basically to let everyone know the party is over, its been completely ruined and I dont give a fuck anymore, im getting high on my drug of choice, I hope you all feel uncomfortable now and im just going to sit here and get high on heroin and do my thing. I was so disappointed the my one and only 30th birthday had been totally ruined by someones pure lack of respect for my fairly easy to follow wishes, and wishes that had pure basis in the fact that something like this would very likely happen and it did. It was such a horrible end to a fantastic few days. But the "Lets take MDMA" comment after just losing the plot was what sent me over the edge.
Thats not the only meth and LSD drama ive witnessed either. I would never in my life take LSD or any psychedelics within a week of my last use of meth. I have smoked DMT I think the day after I used meth and saw satanic writing all over my walls and felt a very, very dark energy that completely flipped my lid and scared me intensely.
Another time recently during my 2 1/2 year long heavy and daily use of mostly IV but smoked meth also, I took some ketamine, and had a full blown psychotic break where I felt I left "The portal open" as in the protective spiritual layer that is opened when we ingest psychedelics but also leaves us open to what I consider essentially possession, was left open and I was vulnerable to bad entities and energy and I lept seeingsequences of numbers that I was sure meant something, I was extremely paranoid and to make it worse, a person who would not interested in their sexual advances basically wouldnt let me leave their house until I got really angry and threatening. I made them call me and uber which took me home and I felt much safer and slept it off.
Id heard of ketamine psychosis but never understood how it was possible until then.
