Intuitively I see all addictive industries the same. The Tobacco industry can, and does, make money off of the odd cigar at a house party. But ultimately, they rely on the constant addiction to have a business model.

It's cheap, and easy, to make nicotine free tobacco like devices. You could lower your cost quite a bit - pretty good for the books! But it doesn't matter, and nobody with half a brain does it.
