I've heard experts on the subject say you could smoke a joint of it the size of a telephone pole without any buzz.
I must say your "buggy whip" analogy doesn't wash.
People stopped using horses & buggies because of the auto.
They weren't taxed, frowned upon, or otherwise coerced and cajoled into no longer using them.
Smokers are giving it up for those very reasons, plus the healthocrats' jihad against it.
I am sure blacksmiths, and the buggy and whip makers only "knew" those buisnesses and had been doing it for generations. I don't know if they went crying to the government for money to keep them in business. But if they did they were clearly turned down otherwise we would still have them around.
I dont want to see tobacco farmer 1 put out of business by the heavy hand of the IFG. I also dont want to see them proped up by the IFG.
To be honest, the tobacco farmers have virtually signed their own death warrants by dancing with the devil (the IFG) for as long as they have.
