Sadly! Drugs are everywhere! Sending him out of state isn't going to stop his using if he wants to use? YOU aren't going to stop his using if he wants to use? He's past the age of 18 too! So you can't make the decisions for him either!
He knows what happened with his older brother! It's a matter of time before he entangles with the law himself! If he's doing things wrong?
You've preached and talked and worried until you're going to put yourself in the hospital or end up on anxiety meds. You have a younger son to care for!
It's okay to worry and be concerned for your older sons! But that's really all you can do! They are adults! They're going to do what they want to do. You can w/h the money and can put your foot down about drugs being in your home.
If they didn't live at home? You wouldn't have a clue what they were doing! As for searching around for something? He could have gotten a girl's phone number and can't find it! Just guessing here!
Try not to assume the worst in every situation!
