I have been vaping since about 2015, when the vape technology was still primitve. Before, you could buy all the stuff off Taobao. Then they removed all sales of anything vape related off of Taobao, so I had to get everything from a private store in Shanghai. Now they are eliminating all sales of tank like vapes, all vape oil.
I went from being to a two pack a day smoker, who hacked and coughed for half an hour every morning, to someone, whom through vaping, does not cough, clothes and house don't stink of smoke, and vaping has no perceptible effect on my cardio vascular system. Also (until recently) much cheaper. But there is no state monopoly on vapes, and vaping related stuff, as there is in tobacco. Now there are trying to shut it down as much as they can. I am addicted to nicotine, though I did manage to quit for a year, 2000 being the year. Now I don't even make the attempt. I know what I am and too old to change. Not even interested.
