Hi LouLou, I am in similar situation, except urban, and my 14 year old was identified by his school as being involved with weed. This was about 6months ago and whilst not “permanently excluded” he had to leave mainstream for and educational support entre. We catch him with an occasional cigarette lighter, but never found anything else on him, and as yet not noticed money or any of our possessions going missing. He is doing well at the new school, andthe main we are praying he has realised that what he chooses to do now will affect the rest of his life and picks the right path. But Occasionally he leaves Facebook open and from some messages I suspect he is smoking weed and I have seen meth mentioned, I was wondering where you got your drug test from, I never thought of doing that as a measure of “good” behaviour.
