Pesko and Saenz show that FDA deregulation led to a boom in e-cigarette research and development which improved e-cigarettes and led to many lives saved as people switched from smoking to vaping.

but what about people starting with vaping and later trying regular cigarettes? If e-ciggs become super-popular this will probably have some bleed or spillover to tobacco products , alcohol, or drugs.
