Australian cigarette smokers were hit with a 12.5 percent tax increase on Tuesday, the second tobacco excise tax hike Canberra has leveled against consumers this year, making the country the most expensive in the world to be a smoker. RT News reports that a package of 20 cigarettes now costs AU$35 (about N$450) and brand-name cigarettes are even more expensive, at upwards of AU$40 per pack. Government officials say they want to discourage the dangerous behavior, but as taxes rise, so does the black market trade in tobacco and according to the Australian border force, the illegal business is worth more than AU$546 million.
