I have been wishing for the same thing. I was thinking that the first "production type" cigarette rolling equipment early in the 20th century might be a good place to start looking. They would likely be simple mechanical contraptions as that was the norm for early manufacturing processes.

I think a five pack of joints would be great. Packaged similarly to the old tobacco cigarette sample packs back in the 1960s and 1970s. But just the ability to roll up 10 to 30 joints at one sitting would be fantastic.
