Ds turns 17 in 2 weeks time. We have had a long battle with behaviour and smoking weed. He agreed that he really wanted to learn to drive and it seemed a really good way to turn things around. I booked an instructor for his birthday and he agreed to go to college and stop smoking weed. Things improved and he stated attending college and he didn’t smoke for a few weeks. During the last week he is back to his old habits. Obviously stoned when he comes home from college. My husband has just been diagnosed with cancer so I’m really struggling at the moment. When he doesn’t smoke he can be lovely but he is a paranoid mess when he starts smoking. I’m going to have to cancel the instructor. I can’t let him drive if he has cannabis in his system. I’m heart broken. He is very loved and has so many opportunities. I thought learning to drive would be a great incentive to stop. His dad is also heartbroken having to cope with our sons behaviour and his diagnosis .
