Regarding vape pens (on planes and in public):
Being a nicotine vapor for the past 7.5 years and traveling with them on planes frequently, I would never worry about taking that stuff anywhere, unless it is determined that dogs at airports do care and can smell small amounts of concealed concentrates...which it seems they don't from what I've been reading. There are a shit ton more people vaping for nicotine than THC & have been for a really long time. They would look like fools if they started stopping people for vape supplies at this point in time in the USA unless they smell strongly like something illegal. Almost all vape juices have some sort of smell on exhale so it would have to have a significant odor to call attention.
If you really want to be super careful (but I
wouldn't worry about it at all, in fact, I plan on taking a concentrate vape pen on a plane for the first time sometime in the next year), try to make yourself look like more of a nicotine addict...LOL...but I'm serious! Especially if vaping THC in public: Vape "pens" are less common among nicotine vapers (these days) than big box mods. You may not like it but it's true. I don't like it but its about functionality of vaping nicotine - bigger really is better. If you want to be really inconspicuous use an e-cig standard box mod (one that is common in vape shops now) and a Sayonara. Saionara looks more like a modern & current nicotine ecig
for sure, than any of the others that I've seen IMO. I wouldn't even know the difference if I saw you vaping on a Saionara with a box mod!! The closer to your body you carry them the more realistic they look also! Remember you are trying to look like a nicotine addict. Think of your vapes/vape pens as something you need seriously fast access to....like cigs or e-cigs if you were addicted.
I also think the Carmex with makeup or other liquids in small containers is a no brainer. They can't (time-wise) just start opening containers of your makeup/cosmetics! They deal with so many tiny containers each day that they are never going to do that. If you worry about that you must not take toiletries on planes very often (guys).
Vape on!! Stay lifted
