You are taking at face value that there ever was a fatal diagnosis.
I don't believe it.
But let's say it's so. There are huge numbers of people who smoke pot who get cancer. They die like everyone else. If pot killed cancer Bob Marley'd be alive today.
Marijuana or components in marijuana very well may have legitimate medical use. But this whole medical marijuan thing is a big ruse. It has been cooked up by the same old counter culture that advocated rug use in the 60's and 70's. It's their latest tact to try and make drugs more readily available. And the main stream media plays along with them just like they do with most liberal endeavors.
At this point, I'm taking the pertinent statement in Mojave's link in comment 9 at face value, for which I thanked him/her, and which I italicized in comment 13 as the pertinent medical history. If there were no medical errors, he should have been dead decades ago with that diagnosis.
I fully understand the arguments in both sides of the WOD, which makes as much sense as alcohol prohibition. My interest is understanding medicine. The WOD has not been helpful in that respect to understanding the endocannabinoid system or optimum medical therapy.
I confess that I glanced over that remark. Cancer isn't a real diagnosis in that the term describes over 200 specific diagnoses which vary greatly in numerous medical criteria. It's obvious that your perspective is political. If a political story involves medicine, I can't ignore medical facts.
