The States need to protect smoking as they win 2 ways: the tobacco tax revenue and the MSA payments. Apparently NY and California are the biggest winners in the MSA stakes, and if that is the case then you can expect the fiercest opposition to ecigs to come from those two states. As it does.
The MSA funds are a fee paid to each State by the cigarette firms to pay the costs of smoking to the state. This income is immense: over $200 billion projected to 2023. At least, that was the situation until vaping came along. That's why the States are doing everything they can to kill vaping.
Smoking is the world's biggest gravy train. Everybody protects it. If they don't, their jobs disappear or they get paid 1/10th their current rate. This is one hell of an incentive
It's also the biggest COI going (conflict of interest). The people who in theory are there to protect you are incentivised every which way to keep you smoking.
The greediest, most incompetently-run States
sold their projected MSA payments off early in the form of bonds. That is going to cause tremendous problems if vaping kills off smoking - so they have to fight any way they can to stop vaping. That's the reason for all the lies, propaganda and legal attacks coming from the States.
