I'm just going to be straight with it. I've smoked meth off and on periodically in my life, snorting burns like hell, hot rails do too (heating one end of a glass tube, or metal, then snorting it, which will make it turn to vapor while snorting which gives you the effect of smoking and snorting, which if done right will produce vapor when you breathe out). I've never touched a needle in my life and I never will. But those are the ways I've done it, meth is water soluble, so it can be put in your drink, and it will immediately dissolve, I knew someone who put it in their coffee.
And so, prior to Covid, I had only ever gone on binges, two to three days in length, or so, and I was done for a long time. I guess I should state, I'm Bipolar I also, and my life has been extremely difficult for the past few years. I moved completely away from where I used to live, to try to start over, and then, literally a month after moving, comes Covid. So, for those who took it seriously, like me, we are supposed to stay inside and away from people. Yet, isolation is the exact wrong thing for most anyone with mental issues. So, in my isolation, my mind went back to all the bullshit of everything that has been going on, and, I found a source for meth.
I've always been extremely careful when using anything hard, and with meth, a little bit really can go a very long way. I don't use the butane lighters, which heat it up so quickly, as many people do, instead I use a candle, which heats it up much slower and allows me to much more accurately control how much I'm getting. And so, after smoking off and on during 2020, and then, as these personal issues just kept getting more and more intense (love, gd f'n love). So, the more intense my issues got, the more I used. Yes, tolerance is definitely part of it, the longer you use, the more you will use. I found a much better source, who gets much better shit, which is something very key, especially with meth, as the lower quality might be cut with no telling what, the purer, the better, and is much safer, for these reasons.
I'm high right now as I write this. And after a year and a half, or so, I've been going pretty damn hard on meth, before this, I had only ever used pot and alcohol on any kind of a regular basis, nothing else, ever, in any kind of prolonged way. Granted, I stayed drunk for about a decade, possibly a decade and a half, and I smoke weed with anything I do, as for me, weed balances me, with any substance I've ever done. Being that I fully understood how powerful meth is, I still smoke extremely lightly, and the only way I do it, is through smoking. I know how it affects me, and I know when I've had enough, or, as does sometimes happen, did a little too much. Which, when my ears start that buzzing, or whatever it is, I know I need to chill out, and I do. I haven't ever gone too far, the longest I've ever stayed up is around three days, usually only two though. I have a system, which I follow, and for me, it works.
And so, how does anything I've said relate to the topic? Honestly, straight out, it really doesn't, explaining things from the perspective of a meth user, was what I intended to do, yet I found myself focusing on my more than I wanted to. So with drugs, everyone reacts differently to everything. There is a certain drug for everyone, that is the absolute wrong thing for them to find. Meth is mine, yet I also understood this extremely well before I started using it again. Sitting in my apartment, I don't even get paranoid, I don't get so full of energy to where I have to just always be doing... something... like is what happens to most people. For me, meth helps me to focus my mind, and I've written a whole lot on it, because of this fact. I typically will sit in my recliner, and mess around on my computer. I sometimes watch TV Shows, I'll try to teach myself things like basic programming, which I am not good at in any way. And just sit, still, not fidgeting, not constantly up and doing shit, just chilling and screwing around on my computer.
Meth, will make me absent minded, in the sense that if I am past a certain point, I'll start doing something, like trying to figure out one specific thing, but I'll end up never even coming anywhere close to figure that one thing out, and go through 10, 20, 50, 100 different things, never figuring anything out, just Googling a lot of stuff with the intention of doing it. Yet, I have always been the exact opposite of hyperactive, and in so many ways, meth affects me in positive ways, such that are things that other people seem to be able to do normally, which I am not able to - at least, not that well. Adderall is the exact chemical composition as meth, except for one molecule, at least from my memory, I'm pretty sure that's true. Which Adderall is a weaker, legal, version of meth. The way meth affects me, is how I assume it is intended that Adderall is supposed to help those who it is prescribed to.
Yet, unlike me, I've done meth with quite a few different people, and not one person I have ever done it with is able to just sit in one spot, still, for any amount of time, much less the entire time. Paranoia is extremely common also, people literally peeping out of the blinds every 2 minutes. People, also, who don't understand how strong it is, will do more than they should, get tweaked out more than they should, and stay up longer than they should. I've never slept a full day, I've gotten close, 18 hours or so, maybe a little more, but I knew people who would sleep for 1-2 days, after their binge. I tell myself I could quite at any time, and I want to believe I can, I've pushed my sober days, being I stay sober longer than normal, to test myself, and I don't get to where I'm phening out or anything, but when I finally use again, it does ease my stress levels, so I know getting and staying clean will not be as easy as I want to believe.
Man, I truly have to apologize, I truly thought I would have much more useful things to say, than what I have ended up writing. I just never could stop talking about myself, and how it affects me. What you talked about her talking about, I've never come anywhere close to experiencing on meth, LSD or Shrooms, maybe, but not on meth. She definitely seems to be in a very bad and unhealthy place. Whether she truly is using or not, from what you said, I'd say very possibly something, maybe even meth, which can be cut or mixed with anything really, so something like that is also extremely possible. When I was in rehab, I learned that when you mix multiple substances, they combine to substantially increase the effects of both things. So, if that is going on, there is no telling what she might be using, or the effects it may have on her. And after my year and a half on this, I'm not much different than I was before I started. But I believe that is due to my intent of getting to a certain point, and not allowing myself to go past it. Many people can't have this kind of self restraint.
Anyways, I hope my rambling helps you. And I truly hope your friend gets help. Yet, on that note, another thing I learned in rehab, is that you can't force someone to stop, the only way it will ever truly be successful, is if it is a choice made by them. Yet that being said, forced detox, might be something that would work, as when she finally gets completely sober, and is able to clearly see and understand how much it affected her, could help push her to that conscious decision to quit, and stay clean. But, it may have the complete opposite effect also, I've known people that have gone to both extremes, one sobered up, and stayed sober, the other isn't with us. Which, is just another reason why I force myself to go easy, as I fully understand what is at stake. I apologize again, I truly did think I would have more useful things to say. I wish you and her the best of luck, as addiction, especially to meth, is nothing but bad.
EDIT:
I had no clue I wrote this much, I blame meth, I just hope something I said can help you and her. Also, yes, absolutely, meth can wreak extreme havoc on mental health, which I have noticed within myself those rare times I do go a little too far. Long term effects, are well documented also. I truly hope you are able to get the person back that you once knew.
EDIT:
Talking about how it has to be her decision, and how her mind has to be made up, it should also be said, that logic and reason are thrown straight out of the window when it comes to drugs. There is no way to rationalize things with her, or to her, people can talk until they are blue in the face, and get absolutely nowhere. She has to want sobriety, more than she wants to get high, which can be extremely difficult to find especially in the depths of addiction.
