Laws vary by region, and they change. What's legal in one state might not be in another. For example, some states have banned flavored vaping products entirely, while others only restrict certain types. Age limits can also differ, with some localities setting the minimum age higher than the federal standard.

If you're traveling with vaping products, it's especially important to check the rules at your destination. What's fine at home could get you in trouble elsewhere. And if you're buying online from another state, the seller is required to follow the laws of your state, not theirs.
