I will vape when traveling since I cannot carry any cannabis flower with me going through TSA. Vaping does produce smoke, although very minimal, with less smell and without the mess of ashes produced when burning flower. It is definitely more convenient and portable. Vaping is considered relatively new and there is no solid history of any adverse side effects to our health at this time. I tried vaping to help me quit smoking tobacco, that did not work, and it cost about the same as buying cigarettes anyway. I quit tobacco in 2020 after smoking tobacco for over 45 years. Happy that I quit and so are my grandchildren. What was the question again?
