Well, I blamed the US vaping situation on the TMSA (Tobacco Master Settlement Agreement) and the bonds for them. Looks like we have our own governmental addiction to tax revenue related to traditional smoking.
I firmly believe that no matter what they do, they are going to lose a VERY large portion of that tax in a very short timeframe. And DIY is dead easy no matter what laws they pass. They're going to have to find somewhere else to draw that tax from soon, even if they try and tax vaping.
