Using real thc in a vape or a synthetic?

You can't fool a real sniffer dog with e-liquid. Even with very strong flavors. Luckily, they are very rare. And those that we usually see with customs are not. They are mainly there to provoke a reaction and thus help identify suspects. Chili, pepper, and others don't work. A waterproof container cleaned with chlorine and repackaged in another net... doesn't always suffice. So it's up to you to decide.

people die from that synthetic shit, please dont even consider it as an option. no mf ever died from cannabis but synthetic thc is a killer. i’d never touch that stuff!

Maybe @Growdiaries know the awnser?

DO NOT cross a border with anything illegal. What type of vape? The small cartridges containing a thick liquid generally need RSO or similar. The viscosity is very important. If it's a dry herb vape you just use regular flower. It does not need to be decarbed since the heat of vaporization does the decarbing, just like smoking it. Just like smoking you get good results with good product. Use trash (trim, sugar leaves...) and you'll have a trashy, low impact vape. I would NEVER use synthetic especially if not purchased from a licensed source since you don't know what is in the powder.
