"Diabetes, hypertension ...were less common in current- and past-smokers."

Perhaps because they weigh less?

Exactly we know both of those diseases are affected by weight and smokers burn more calories due to the nicotine in their bodies.

Of course lets not bring Lung Cancer, Pancreatic Cancer, or the plethora of other diseases where the increased risk of developing due to smoking is hundreds of times that of the non smoker into the conversation.
