oversmoking

Oversmoking refers to smoking tobacco or other substances to excess, beyond what is typical or advisable.

The term appears most often in discussions of health risks or addiction, where someone's consumption has crossed from moderate use into harmful territory.

His oversmoking had yellowed his teeth and left him constantly short of breath.

Less commonly, oversmoking can describe a culinary error where food is exposed to smoke for too long, resulting in an unpleasantly acrid flavor.
