Do you have any source on that? The only reason I ask is I've heard that rumor many times over the years. In particular I had a civics teach in high school tell me how as a student he had gone on a tour of a Phillip-Morris (or some major tobacco company) facility and supposedly was told that they were amassing equipment to make Marijuana cigarettes because they thought it was going to be legal in a few years. Seeing how the man was in his late 50s that story has been going around for a while.
