re: #233 Dr Lizardo
The economics are going to be interesting to watch. I recall an old urban legend from when I lived up there near Portland; namely, Philip Morris had a patent design ready to go for a tailor-made joint with a filter, just like a regular cigarette, and even had gone so far as to create packaging for it, should marijuana become fully legal in the US.
I heard that well over 20 years ago, so that particular urban legend was likely floating around well before that.
That sounds familiar, I think that one is still in circulation.
