When you're looking at a site that sells CBD-compatible vaporizer hardware, age verification is a good sign. It means they're serious about the law. In Japan, for example, selling vaporizers to minors is illegal, and responsible retailers will check your age at checkout. You'll see a pop-up asking for your birth date, or they might ask for ID if you're buying in person. That's a green flag. It shows they care about compliance, which usually means they care about other things too, like product quality.

Another green flag is clear language about age requirements. If a site has a page that says 'You must be 21 or older to purchase' or similar, that's a sign they've thought about this. They're not just trying to make a quick sale. And if you see a verification system that actually checks your ID, like a government-issued ID scan, that's even better. It's a bit of a hassle, but it's for your protection and theirs.
