My son is 28 and from the age of 17 was smoking weed regularly, taking cocaine and ecstasy occasionally. He became Psychotic and was sectioned, long story but now has Schizophrenia. He was completely drug free for all this time, which I was very proud of as most of his friends were still taking all sorts of drugs. Recently he confessed that he had been using cocaine , but said that he didn’t want to go down that road again so wasn’t doing it any more . He has still been taking it at times which he has confessed to I’m staying at his place tonight, which I’ve never done before and someone knocked at his back door. When I asked who had been at the door he denied anyone had knocked. I’ve got a sick feeling he has just bought cocaine even when I’m in his house. I feel sick to my stomach as he has now turned into a liar and I don’t think I can go through all this again
