I wish renting vapes were possible lol, there's a lot of cheap weed available in some cities ($1-3/g) that can actually be decent so it's easy to get a lot for cheap.

If you have the budget for a spare vaporizer that would probably be your best bet for flavor and ease on the throat. You can also get some cheap glass at a lot of places and have a little pocket bubbler with the vape (just make sure it's 14mm female or have an adapter! I usually use a bit of silicone tube)

Edibles here are pretty cheap too sometimes, though they personally don't hit me and they'll all 100mg max.

Finally - I've flown with multiple vaporizers! I'm not sure which you have, but if you're able to disassemble most of it or remove the batteries and keep them separated in the device. Cleaning the bowl and mouthpiece with isopropyl alcohol and getting it to its "factory" state effectively turns it into any regular old aromatherapy/tobacco vaporizer.

General rule of thumb I use is self-contained, declared, and carried on. I put any accessories (mouthpieces, all batteries, etc) and the vaporizer body disassembled and in a pelican case. I take it on carry-on, let them know the batteries are internal or removed, and then they usually open it and inspect it taking every piece out looking at it and then putting it back and I'm on my way. Hardly takes any more time than usual TSA! That said, I can't speak to how this is for non-legal states. I assume dry herb vapes are just dry herb vapes, but ymmv and I understand not taking the risk on money and time.
