Kids don't have to hide proof of their consumption in their bedroom (well at least until they are hooked enough they can't spend a night without vaping). They buy, consume and throw away before reaching home.
Your point is quite valid, but example is wrong. Those vapes can have a lot of puff in them, they need to be really heavy smoker to smoke out in 1 session.
But reuseable vape has more stuff to manage and hide, and they are more expensive in short run.
