Benefits of breaking the habit

If you need a cigarette when you wake up then it’s more than likely that you’re addicted and should make a serious effort to give up. If you’re a social smoker – say one or two at weekends or at parties – you should still try and give up completely. The good news is that the benefits of giving up smoking start immediately.
