Yes, the pill packs that are pictured in the previous posting is the ones I use. You want something that you can label in advance and the customs officer would have an idea of what it might be. You just use dozens of them until you have all your pills packed. And then I put all of them in quart size Ziploc bags. To double secure them. I've never been stopped by customs and I've been doing this for years. Since 2013.

The thing with drugs, most agencies have field drug tests and also drug dogs. If the dogs don't detect anything then they won't further check, but if there's a detection they will field test suspected ones. Any of this happening would be almost zero chance. Having them in pill paks are the best for labeling and the paks are for pills, not a Tupperware container.
