he also could have not used illegal drugs but instead getting addicted to the medications that u cant get without dr's written paper or whatever. that case ....the one u were talking about... my sister was exactly same way and shes addicted to codine (painkiller medication) and she denied it every single time even though lot of us found it hidden somewhere in her house.
another thing... that person also could go through depression. and cant take it anymore... theres so many things that can change a person's way of dealing with the life and everything else. so dont rush and decide he must be using illegal drugs. theres way too many things that can cause him to act like that.
just wanted to add that just to make sure you know theres more than just illegal drugs that can make a person behave differently. Also a broken heart can cause that ... stress daily wiht no break... difficult with sleeping, etc etc etc... make sure u cancel those out before u can decide he certainly is using drugs. ok?
