I wish I could give you a very firm answer and that we had very well-specified and good models for predicting and relating quit rates to the prices. It's not always possible, because the past isn't necessarily a good indicator of the future in this case.
For example, far fewer people are smoking now in Canada, and the nature of those smokers is a bit different. You're down to the hardcore smokers now, in contrast with many years ago, when people were recreational smokers, if you could call them that. You have as well very different options, such as vaping. We didn't have vaping options years ago either.
It's difficult to draw a fine line and be very specific when it comes to this sort of question about translating the dollar increase into the quit rates. All I might do is reiterate my initial remarks: Tobacco taxes have gone up over the years and quit rates have also been maintained. The smoking rate has dropped from about 25% to about 15% since 1999 or so.
