The few that do lose their rationality lose it because they don’t sleep for weeks. They likely also live in an unsafe environment which keeps them in a perpetual state of survival stress.
Survival stress + not sleeping + stimulants —> psychosis. Very rarely any of these alone, unless the individual is predisposed.
Asking because THAT fucks up people and makes them use drugs to escape their situation.
Survival stress, as in PTSD, causes cortical thinning, and explains everything in the scenario without the need to arbitrarily assign blame to methamphetamine.
I would agree with you in general, but there are situations where prescribed methamphetamines also lead to cortical thinning when not used as recreationally. This seems to suggest that stress may not be the entire player here https://www.ncbi.nlm.nih.gov/pmc/articles/PMC3870784/
It was likely decided because of the dose of meth found in the persons systems that correlates with various findings on dose-dependence https://jamanetwork.com/journals/jamapsychiatry/fullarticle/...
If you would like to read more about PTSD findings as it relates to stress and liver function, I would be happy to expound upon the way that corticosteroids impact gut bacteria that directly affect FXR metabolism and bile acids and further lead to cortical thinning. https://academic.oup.com/cercor/article/30/2/575/5521088
Its really fascinating how a drug like methamphetamine impact neuroactive steroids that impact the same pathways tha stress does. https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6862925/ We've been able to reverse it in rats https://www.sciencedaily.com/releases/2013/10/131007093739.h...
I suppose I agree that environmental stress, survival stress, and PTSD are all common in the addict community. That’s true.
In my experience though, meth-induced psychosis is a thing. For example, if you understand the following sentence you either have seen or done it!
I once snapped/ghosted 3 points in one draw in order to scare off some gangsters, then the shadow people came.
After that I thought I could talk to programming libraries out loud. Not in a fun way. Meth induced psychosis is absolutely a thing.
Now, if those symptoms persist after you (would) pass a piss test, then we are talking about meth-induced psychosis.
