yes -
I admit it is morally complex. I became hooked on cigarettes during he time tobacco company's were suppressing the data on the extreme health risk of tobacco. Thus they deserve some blame for my, and millions of others, addiction.
But, in a way I am still buying from them and supporting them in that I am vaping nicotine, which comes from the tobacco farms.
Thus, even though I am not now buying cigarettes, I am still a user of tobacco products, thus supporting tobacco companies.
And, even though I do not support the Chinese government, I am buying most of my vaping equipment, and much else, manufactured in China. So, whether I buy from a Chinese firm, or an American tobacco firm, I am supporting companies I find morally repugnant.
