Bob Packham, deputy director general of the National Crime Squad, seems to me to be in a state of confusion. He understands, correctly, that cannabis - along with the hard drugs - is supplied by criminal gangs. He also rightly understands that ignoring the present law on possession of cannabis will allow the trade to grow. But he doesn't seem to have grasped that the trade has expanded because cannabis is illegal. Something which is demanded by such a large section of the population will be provided. If you don't allow a legal supply, then you'll have an illegal one. If he is really concerned about closing down these gangs, there is only one way to do it - put them out of business economically by allowing a legal, regulated trade to undercut the illegal market. Yours sincerely, Derek Williams, 21 Pembroke Road, Norwich NR2 3HD.
