Any gov powerful enough to ban the juice is just as capable of banning the vaper.
Good luck.
In the EU we already have all kinds of regulations since the TPD (Tobacco Products Directive) in 2014... so what? They can't ban PG, VG and food graded flavors, nor rebuilding materials.
If the gov will ban the whole vaping business, including China, well, the DIY-types will make their own vape machines, and others will buy second hand mods, RBA's, RDA's, RDTA's.
I've got about 15 tanks, 7 drippers, 3 mods, 2 mech mods, lots of VG, flavors, wire, Muji cotton, tools, ...enough to survive 6 years.
