The PHE report summarises our understanding of smoking in prison. On the one hand, limited access to tobacco can reduce how much and how often prisoners smoke as can the cost of tobacco for those surviving on a prison income.
Conversely, smoking is often seen as a coping strategy to manage the stress of imprisonment and helps to alleviate boredom. Not smoking in a culture where a large majority of people smoke can also be socially isolating. And, of course “Burn” remains one of the principal prison currencies.
