I don't think any of those really mention the number of smokers. They discuss the impact on the tobacco industry, which can make up the income in price difference on top of the lower-than-expected tax. The second article says only that not raising the tax higher means some people decided they're ok with the cost.

But neither one really shows that the prevalence of smokers pre- and post-tax hasn't changed.

In terms of numbers I can only find the 2016-2017 GATS numbers of 28.6% users, 10.7% smokers.
