Diabetics using insulin should be advised to monitor blood sugar levels regularly when cutting down or quitting tobacco. The advisor can continue to supply NRT products, but should also seek consent from the client to notify their GP or an appropriate healthcare professional about their quit attempt, as well as informing them of any relapses and returning to smoking.
