I would suggest that he goes onto CA – cocaine anonymous and you can join a group chat where he would be able to understand and talk to people who have stopped taking cocaine – it is done online and he can just listen or participate. You can also go online when it is an open forum and talk to recovered addicts – they are really welcoming and I found it very helpful to see it from their point of view. Your husband can go to as many zoom groups as he likes – I think they recommend 6 in total even if he joins different groups from all over the country and then finds the one he likes most and joins them weekly eventually. My husband was taking cocaine behind my back and for goodness knows how long. I bought some cocaine testing strips from amazon and secretly tested his urine that he left in loo to stop waking me in the mornings and it was positive for a long time until I told him that I knew – I really hope you sort it and find peace. I THINK my husband has stopped as he swore on oath that he wouldn’t take it again once I confronted him. I have secretly tested him still and it is negative but I never trust that he won’t take it again. I hope this helps x
