It is as hard to give up smoking after two years as it is after twenty, so don't expect it to beany easier for him than for an adult. The boy surely already knows the down sides of smoking - it's pushed at them so much these days, it's hard to ignore. If he genuinely wants to give up, his GP can help. Many surgeries these days hold special clinics for people trying to kick the habit, and GPs and their staff have a remit to support people who want to pack it in - it doesn't matter how old someone is or how long they've been smoking.
