Sounds like a dangerous place to work, pimps, no support organisations/government.

I am a sex worker too (in New Zealand), there are a lot of drugs around, and a lot of girls who imo shouldn't be working in the industry because they can't handle it/ don't like it/ are going against their personal beliefs by doing it and are only there because of unfortunate situations/events in their lives. So a lot of girls do sadly get really fucked up like that. Some may have only gotten into sex work to begin with to support an existing drug problem. I feel like I'm being sexist saying girls because probably the same happens for male prostitutes but I have never worked where there were any so I can't say.
It's especially dangerous if they are getting super fucked up
while at work, what if they are assaulted and can't defend themselves, or if a guy can slip the condom off without them noticing, etc.
I use drugs, and if I'm at work and a guy buy buys me a drink or gives me a little something, if I can tell what it is obviously and they've had some first, I will sometimes accept a small amount, because if that's what they came to do and they think you are "partying it up" along with them they can end up there for many hours and you earn a lot of $$, if you are not the party girl they were after they can feel uncomfortable indulging alone and may swap you out for a different girl after the first hour and she will earn a lot of $$ instead. But I never get drunk or twisted while at work, I'm far too scared! You have to be aware of everything going on to keep yourself safe.
Of course you don't
have to take drugs or alcohol at all while you work, I had been a sex worker for four years before I ever even tried a cigarette I used to be anti-drugs! Lol, I remember at school if someone had a cigarette down the back of the field I'ld say to my friend "look down the back of the field! They are like totally smoking, omg!" I didn't try any drugs until much later when I learned a bit about them and stupidly thought I could use them to lose weight, and also was curious and wanted to experience the effects (this reason I don't have a problem with).
I like to get fucked up only in my own time. Almost always at home, where I feel safe. I've had a few benders in my time! But never really gone too hard out because I've always been the worrying type and I always have the fear that I will develop an addiction, also the $$ because I'm lazy and don't tend to work often. I'm not sure if using one weekend per month is consistent with most people's idea of what addiction means, but this is what I do with meth and I have decided to quit this particular drug in the past and then changed my mind to allowing it again so maybe that means there
is an addiction here after all. I'm not entirely sure.
The other possibility is that I just get bored as I have no life, pretty much. I just work when I need to and then sit around the house relaxing, interneting, cat petting, might do some reading or painting. I don't like the stress of the modern busy lifestyle and I'm grateful I'm able to avoid it. I get up when I'm no longer tired, I have nothing to set my alarm for. If I don't feel like going to work I don't go and I don't get told off or anything. I do what I want when I want which is generally nothing & always lol. I don't know why I get the urge to actually DO something or take something "fun" once a month, maybe it's tied into my hormonal cycle somehow, but there's never anything interesting/new to do or anyone I'ld like to do something with. I can't even get different drugs to have fun with because I don't mix with the people in the drug scene much, and don't really want to as have seen some nasty goings ons within it. As meth is the most common drug where I live it's the only one I can access easily so I do.
I'm also possibly addicted to ephedra based diet pills. I take these everyday.
