... I just don't think the TSA is looking for pot.
Sorry to clip the rest of your entertaining post, but this is the most important part for all. They're looking for other things, and not drugs at all unless you're carrying a lot!
You really want to get harangued? Have more than a 1/4 cup of some powder in your bag. Doesn't matter whether baby powder, protein additive for "healthy" drinks, or anything else. A friend I was traveling with had some whey protein in an unmarked container she had forgotten about in her carry on (leftover from a trip by car the month before). They had her off to the side for more than 30 minutes, even though she started the whole ordeal with "just whey protein powder and not too much, you can throw it out". No way, no how! They rubbed down the container, her bag and her with all kinds of explosive detecting wipes. They dumped a little of it into a plastic bag that had some other powder in it, shook it around and looked at it like they were on CSI. As we were finally getting out of there, they had just escorted a woman off to the side and were pulling out her shower to shower powder!
I wouldn't push them too far, and better to not have anything on you. But a pre-rolled or 1/2 gram stashed here or there isn't going to raise an eyebrow unless it is right in their face while checking out something else - like a butane jet lighter! But, that's a different story!
