You said something different. I said...
"There has never been one death attributed to the thoughtful use of marijuana"
There is nothing thoughtful about buying something mostly unregulated and running up to a room with a balcony to eat it - obviously an unsafe environment. There were other illnesses, obviously, also in play (one already had script medicines, easily could have been for psychiatric disorder). Was there a history of spousal abuse? Those behaviors are atypical for this particular drug, and while this is happening at least tens of millions of other people are using it safely, which makes one wonder why these are so wildly different?
And the other big thing - when you add this drug into a population and look for the things you mentioned, such as suicides, sudden death, auto accidents, the kinds of things common with, say, Oxycontin or others, the numbers are statistically insignificant. The increase just isn't there. All those things happen whether the cannabis is there or not.
So, great for conversation at a donut shop, not so good for sick people needing relief, and it would be useless to base policy on. Fortunately, most people have learned one or two things since 1936.
