As I travel from airport to airport and in flight and then have rental vehicle, can I vape anywhere? Are there any specific rules I need to know particular to each of these states, Denver Colorado-airport, Portland Oregon-destination, Vancouver Washington-where I am staying, but traveling via rental car between Washington and Oregon? I can be very discreet and no one even know I have taken a hit from my vape. I have not flown but once in my life, so, this is an adventure, but also makes me a little nervous, especially going without my vape. I quit smoking 4 years ago and my vape keeps me sane. I have gone into bathrooms in libraries, hospitals, etc and no one ever knew I was vaping. I will be gone for a week, so will take 3 small bottles of juice. Only taking a carry on bag and a personal bag, so will put everything in my carry on in a zip locked bag. Any advice will be greatly appreciated. Thanks!!!
