I would think so, but wouldn't the settlement against tobacco set a (perhaps incorrect) precedent?
I was no fan of that, either, for the same reasons.
(I learned to work on my grandfather's tobacco farm and baling hay for my great uncle. The plant that was, at one time legal tender in the colonies *you could pay your taxes in tobacco* is now rarely grown where I grew up, and then by the Amish who signed no agreements and took no payments not to.
What I found to be a scam was that the Feds did a big study that resulted in listing brands and varieties by their nicotine and tar content. For the sake of consistency, burn characteristics, and desired flavor, tobaccos are blended in cigarettes and pipe tobacco. Those blends had to be manipulated to
maintain the tar and nicotine content, flavor, etc. found in the Federal study, otherwise the tar and nicotine content could vary wildly. Then the Feds sued over maintaining the levels of tar and nicotine in specific brands and varieties.
No medicinal value was credited to tobacco, even though it offsets some symptoms of shock by constricting peripheral blood vessels and redirecting blood volume to the core organs. I have seen lots of accident victims get shaky and smoke a cigarette. (If you will recall, the newsreel images of wounded troops (some with upper torso wounds)
smoking a cigarette while being evacuated, and a number of troops who started smoking during a combat tour.
There are other properties (antibacterial, for instance) as well.
Little else got the scrutiny tobacco did as a carcinogenic agent. Even though smokestack industry emissions peaked and declined about the same time cancer rates did, the credit for the decrease was given to reduction in the number of smokers. Once the desired deep pocket answer (Eeeevil Tobacco, the demon weed!) was found, it is almost as if those researching the cause(s) of lung cancer just stopped looking to see if there were more.
But I never thought I'd see the day when weed was as or more acceptable (despite smelling like skunk) than tobacco.
