buy any bottle of dietary herbs that come in capsules - skullcap, damiana, holy basil, anything.
Chop your herb on a cutting board with a sharp knife, or grind it in a grinder.
Empty a few capsules and replace with the gram. A gram should fit in 2-5 capsules, depending on their size.
Throw them back in with the bottle of herbs.
final step: break open a few capsules into the bottle of capsules.. If it is a powdery herb, it will coat all of the capsules in the bottle..
When you get there, wipe off the capsules to find the pot-filled ones.
This has worked on airline flights post 9/11.
