I’m not well versed on cocaine, but Ketamine is a tough one. It’s very addicting because of how therapeutic it is. The person I know who is addicted to it says that it’s like an “off switch” for their brain and just calms them down. It’s destructive though because tolerance is established quickly, and the addict has to take more and more to chase the high. Plus, the effects don’t last that long, so one bump can only give you an hour max of high. In that case, regular users can go through grams a night.
I don’t know if it’s reassuring to you, but death from ketamine alone is rare. So the likelihood of the worst thing happening is very very slim. I know that was calming for me to find this out. However long term physical damage is possible. Do you know if he’s reached the point of k-cramps yet? Ketamine affects the bile ducts, pancreas and gallbladder, and after a while he might start getting gallbladder related pain, vomiting episodes etc. Ketamine can also cause bladder spasm and urinary retention, it’s similar to a condition called painful bladder syndrome if you wanted to know the symptoms. K-cramps are terrifying for the user and the person witnessing them. The best thing you can do in that instance is call an ambulance and take them into a&e for pain and symptom management. K-cramps are often the users rock bottom and a catalyst for change due to how awful they are.
There are some harm reduction practices you could encourage him to do if he’s not ready to seek sobriety yet. I will say though, be careful here though as he might interpret you taking care of him as enabling him; only you know his mind and if you helping him to engage in harm reduction would do more harm than good.
The balance between care and love and enabling is a really tricky line to walk. Does he talk to you at all? I find that if I approach the subject I get stonewalled, but if they want to talk and bring it up, I get a lot more open conversation.
For you though, the priority is to try and disengage emotionally. Otherwise you will combust. You have to be strict with yourself, if you start thinking about it and spiralling. What can you do instead? What are your interests? Do you like TV and movies? Reading? Do you have any pets?
Also do you have any support from family or friend? Ketamine addiction is an epidemic of terrifying proportions for young people. It’s more prevalent than many realise. So many families are suffering and struggling; many in silence due to shame and fear of judgement.
I’m sorry this is so hard for you, I really do understand.
