My brother went through this in his early twenties. He was unemployed for years and my mum supported him and his cannabis smoking by giving him hand outs all the time. His friends all seemed to do it and i don’t think he realised how serious it was. he was caught with posession and had to go to court. Dad was really strict and condemned her for giving him money and sticking up for him but he stilled lived at home. I came back from uni and noticed a big difference in his concentration and he was anxious and didn’t seem to focus on anything. It’s been a few years now but he’s got thorugh it. He confessed himself one night that he’d ruined his brain with cannabis and i think that point he decided enough was enough. It’s about 5 years now since he stopped smoking it and we’ve got him back. he’s focused. Working full time after a good few pushes as his confidence was rock bottom and i just wanted to say there is light at the end of the tunnel. I think employment is a big factor . Good luck
