But a study by researchers from the University of Bath, UK, and Johns Hopkins University, USA, reported that this approach was subsidising the tobacco industry, undermining public health efforts and reducing tax revenue.The researchers examined the impact on product pricing after a different approach was taken in Ukraine, where the government has taxed HTPs at the same level as traditional cigarettes. The study focused on…
