Expelling children from school for possessing or smoking cannabis is a ridiculously extreme punishment. It is a nonsense to punish an activity that is illegal because of the (very small) risk that it may ruin someone's life by taking action that will certainly ruin that person's life in a far more serious way. Most teenage children take illegal drugs at some time. The vast majority are none the worse for it. I do not condone this, any more than any other illegal activities teenagers get up to, but it is ridiculous to pretend the facts are otherwise. The problems of identifying offenders means only the tiny minority unlucky enough or silly enough to get caught will be expelled. But logically, if we are to expel any teenage children for this activity, then surely we should expel all of them. DAVID WRIGHT Yew Tree House Longparish, Andover, Hampshire
