and now wish I hadn't. Nearly 15, clever, lazy, does OK at academic school, obsessed with computer coding. Messages threads with three different friends have ds arranging to buy weed, some kind of 'legal high' called md, also laughing gas (!). Clearly he is instigating this, and persuading friends to try stuff out. I have not told him I looked, (or mentioned it to dp) but feel I absolutely must have a conversation with him about what he is up to. Where to start? What to say? Help!
