I think it would be ironic to talk to somebody pulling on a vape, and ask them about all the things that they avoid because they could cause cancer. 

Like, “do you prefer the plastic that has no BPE? Do you prefer paint that has no lead? 

Do you avoid taking medication's which could cause cancer? Would you be willing to live in a house positioned under interstate powerlines? 

Do you eat organically to avoid chemicals in your food?”

All the while, watching them, inhaling chemical-rich steam, deep into their lungs, which contain chemicals that literally no one has done the research on, to see if they are hazardous to the most sensitive organ in our body. 

Well, now, or wait a minute, I suppose you could say the brain is the most sensitive organ in the body. But that's not working in this case.
