Not about the size, it’s about the capabilities of the search.

A drug dog is not going to trigger money because of trace amounts of narcotics.

Besides, I’m just amazed that the comment section wasn’t full of people saying they’d put it in their secure stash.

A stash in or around your residence is not very secure by the very nature of proximal association. If you’re going to get this serious about it then a proper secure stash would be accessible but not readily associated with you and not somewhere you go often.
