I travel pretty extensively, flying around 35 round trips a year. I usually carry some dietary supplements with me in a tupperware container sealed in a ziploc bag. My wife has said on several occasions that that sure is a suspicious looking powder in my suitcase.
My suitcase has been opened numerous times by TSA personnel without any problems, but has anyone ever been detained based on TSA personnel finding drugs, or substances that look like drugs, in their suitcase? I’m not talking about customs agents, when I travel overseas I leave with a factory sealed container, and abandon it when I return.
