I don't know what country you live in Casey, but I'm pretty positive there is no such thing as a "Legal Smoking Age" in the United States, at least no where I've heard of. There is a legal age to BUY tobacco products, which is 19 where I live, but there is no law against smoking before a certain age anywhere in the US. No cop will cause trouble for you.It will work for anyone. I think they say it's intended for those 18 or older is because 18 is the legal age for smoking. If you blew smoke out of your mouth and a cop or adults were near by they would think it was actual cigarette smoke and you would probably get in trouble. It says INTENDED for those 18 years of age or older, so I think even though you are 14 you can still get it. I come to that conclusion because it doesn't say ONLY for 18 or older. It says Intended. I think you're good. Just be careful when you use it.
