I Have a foreign travel coming up. I am looking for the safest idea to travel with a vaporizer. I can get oils in the destination country but i would then be flying back via London, and spending an evening there. I would love to vape between airports and then in the hotel room in Gatwick before my flight. I am not usually doing oils but this is the best way including the odor for where I am staying in the destination country. I could also get oil in my home country. Should I just take one vape cartridge with me? I was thinking it's less of a risk to only take something one way. On the outbound also passing through London probably will not consume as I am meeting old friends who do not partake so it would be a bit awkward. I will not be able to get the disposable cart where im travelling to.
