Smoking in crowded public places is inconsiderate and can affect the health of others, but it is hardly criminal behaviour, and most smokers are courteous enough not to do it.
Of the 17 per cent of New Zealanders who smoke, I have no doubt most are well aware of the risks they are taking and want to quit.
When you have known the habit, cigarettes are the go-to fix in times of trouble, no matter how much they cost.
It was the first thing I reached for after experiencing a 7.1-magnitude earthquake in Christchurch in 2011, even though I had given up five years earlier.
It has been very difficult for me to quit again, so I can only imagine the distress of a person experiencing a mental health crisis being banished from hospital grounds to have a smoke.
Providing support for someone to quit smoking is always laudable, but denying a cigarette to someone in crisis is cruel, not to mention dangerous.
I am glad our smoking rates have decreased and I'm pleased to be able to donate some of my personal tobacco savings to a couple of worthy charities.
What I would like to see now is a government that will impose an alcohol levy as severe as the tobacco tax and use the revenue to fix our broken mental health system.
