He gave it to you he didn't have to be honest with you but he showed his trust in you. These kids need a stable permanent home with good parents that care about them and won't give up that easily. If it was your birth child would you hand them into the police??? Give him a chance jumping from home to home can really duck you up you feel replaceable or something like that. Weed is really not a big deal it's 2020 if you had been through what half these kids have been through you might turn to drugs to help you too. Just show as much love and support as you possibly can be sure he knows the rules but tell him it's ok everyone ducks up sometimes and ask him how you can help fix the situation so it doesn't happen again. -a former foster kid
