Dear All, A bit convoluted this but my sister in law's friend's son wants to join the army and she's been asked to provide a character reference. She has asked me what sort of things the army might be looking for and I gave some advice. Having probed a little furhter it turns out this lad (17 or 18 years old) has a caution for possession of cannabis. Is this a show stopper in terms of his army ambitions? Many thanks JB.
