(Indeed, the evidence that marijuana is effective in reducing physical pain among its users is totally anecdotal to my knowledge.)

Uh, duhhhh. What machine is there that measures pain reduction from aspirin, opiates or any other pain killer? The author's a dunce.

"What machine is there that measures pain reduction from aspirin, opiates or any other pain killer?"

I believe the author is pointing out that no scientific pain studies have been done with smoked marijuana as were done with the other pain killing drugs. (Kinda hard to do with smoked marijuana if you think about it).

All we have are similar to what you see posted on this board -- "My neighbor, who is a gazillion years old, said marijuana makes her bunion pain bearable" and "My sister knew a guy with cancer who said marijuana ..."

You get the idea.
