Should we tell our dad about my brother's drug use? by WorriedsisHi, so my brother (mid 30s) has admitted to me and my sister (both in our 40s) that he has developed a drug problem. Started years back with prescription pain meds, which he stopped, but recently (last few months) has now started taking a whole range of other drugs, including coke, ketamine, all sorts, and using xanax to cope with the come down. He stayed with me for a week to get away from temptation, which mainly worked, but has gone back to his flat and is using again. He went to a local drug service, has been twice but I'm not convinced he's going to go back. Our mum knows, the strain on her is awful, we are all struggling. My parents are divorced and my brother refuses to tell our dad about it, but as my dad doesn't know he keeps giving him money..thinking It's going on bills when it's going on drugs. Should we tell our dad? My brother won't tell him but his giving him money is not helping. Also I keep thinking if the worst happened (my brother gets seriously depressed and suicidal) how will my dad feel knowing we've not told him? But then, my brother might not trust me again if I tell dad. It's all such a mess. I'm worried about the impact on everyone, including my 2 young children, who love their uncle but I need to keep them safe.
