I understand e-cigarettes are supposed to help you quit
They’re not.
An e-cigarette is just like a normal cigarette, but you’re not inhaling burned paper. If you were inhaling addictive substances with normal cigarettes, nothing is stopping you from doing the same with an e-cig.
Do they work? In the sense that they “burn” (in quotes) substances and let you inhale them, then yes. That is their purpose.
Exactly. If you can’t afford an expensive lawyer, the US wants you to lose.
Actually, it’s not only that they want you to lose. It wants the entire system to be so expensive that you can’t even afford to go to court and lose. You have to settle, and don’t have a lot of power determining the terms.
