The generic tylenol and tylenol pm just have numbers stamped on them which was a concern, but you're right, it isn't white powder! I do remember one time putting some Tide in a zip lock bag to take on a cruise. My hubby saw it and said, "Do you really want to jeopardize our trip by taking that stuff in a zip lock bag?" I saw his point. This was way before 9/11 when security got so tight. I guess he was figuring that my staying in a Mexican jail wasn't the way to spend a vacation!!!!
