I am new to this forum so first of all I want to say Hello all! The reason I have come here is to find out from first hand experience the long term affects of recreational drug use and hopefully someone will be able to answer my question(s) My story is a relatively simple one that will most likely be very relatable to a lot of people on here. I am 24 years old and for almost 7 years now I have been a recreational user of drugs (ecstasy, cocaine, mdma & ketamine) I also used to smoke weed often. From about 15 years old until August this year. It started as once a week to a few times a week to then everyday from 18 onwards however with breaks of sometimes a week or two or a month or maybe two months in between. I haven’t touched an ecstasy tablet in over two years as the last time I was very very sick and have never had the urge or want to do them since. Can’t remember the last time I touched MDMA. In the last 2 years or so it has been ketamine or cocaine - probably more so cocaine I take recreationally. When I say recreationally I don’t mean every weekend for the last 7 years from when I first started taking drugs however there has been ‘periods’ where I have every weekend over the course of a couple of months or whatever. Out with these periods its been mostly once or twice a month with a few weeks break in between or maybe a couple of months in between here or there. I will add that on each occasion I’ve taken drugs its when I have been drinking alcohol also. Now I read things online that say that substance abuse can ruin the parts of your brain that produce the natural chemicals like dopamine & serotonin permanently and thats what brings me here. At what stage of drug use does this happen? Could it be possible this has already happened to me? Or would I need to be a heavy user daily for years on end for this to occur? Genuinely interested to know if anyone on this forum has any knowledge on this side of things which can help me understand. Thanks!
