Where smoking ban increases immediate risks to personnel

More light blogging. This one concerns the approaching smoking ban in New Zealand prisons, due on 1 July. More than one opinion piece has suggested that prisons are poorly staffed for managing tense situations. Changing the law to prevent prisoners from smoking, while protecting prison guards from whatever ailments smoking might give them, is likely, according to the union (which officially supports the principle of a smoke-free workplace), to make their work increasingly difficult especially in the first 24 hours of incarceration, the period when most prisoners are at risk from self-harm. Officers frequently find supervising prisoners during this period traumatic. Another association has asked for riot police to be on standby.

Is it really worth it?
