Hello have just recently found out that 18 year old DS has been experimenting with hard drugs, he has ADHD and allergy problems. We are working our way through the ADHD and so far going ok, and are starting to address the drugs issue, but he has booked a ‘lads’ weekend in Amsterdam, I appreciate he is now an adult. but is still living with us. We have always tried to be reasonable but with this new information I feel we can’t let him go. Any advice appreciated.
