What are those units of measurement and how do you check them on a tight budget if your using black market? Also do you know much about risks using this technique for people with mental health conditions that make them prone to mania or psychosis? (Bipolar, Schizophrenia, BPD etc.)
ug=micrograms, or 1 millionth of a gram. typically acid comes in 100ug ‘hits’ but this is optimistic, good acid is generally about 75ug. some acid (like the very popular rainbow gel tabs available of late) can be up to 125ug.
the way you find out how it’s dosed is to buy a few hits (or more if you trust the person) then cut a single hit into 4 pieces. eat one of the 1/4 pieces with no tolerance and hopefully without other drugs in the mix to cloud your perception.
if you don’t feel it at all then it’s dosed at less than 100ug per hit. if you feel a speedy effect but not really tripping, hits are probably at about 100ug. if you have a legitimate trip from 1/4 hit, you have unusually strong acid (not too likely but you should prepare for the possibility that this experiment could turn into an actual acid trip - so make sure you have about 12-20 hours free!)
this method uses the known, typical threshold dose of LSD (20ug-25ug). obviously there are lots of variables, but in my experience this gives you a metric to start with at least.
as for the mental health concerns, psychedelics are definitely generally discouraged for those with a family history of schizophrenia because they are known to trigger symptoms of schizophrenia in those who would have developed it anyway. I do remember finding some research once suggesting that if schizophrenia does not manifest by one’s mid/late 20s then it is not likely to manifest later in life.
I couldn’t tell you about the safety of taking psychedelics as a diagnosed schizophrenic though. I would imagine if someone is stabilized on antipsychotic meds those could interfere with the effects of a psychedelic, but probably would only lessen the intensity. as far as mania/bi-polar disorder, I really don’t think that acid would be any more potentially dangerous than meth or a number of other drugs.
all of that said, acid has some very unpredictable subjective effects sometimes, even at low doses. it is physically benign, but can certainly cause psychological issues (the most worrisome in my opinion is a condition called HPPD). if psychs are something you aren’t already familiar with, I would tread lightly at first. it’s unlikely to cause you any real problems, but of course be careful.
