Looks like a theory at this point, and cures for cancer are all suspect while cannabis is being ignored/prohibited, in my opinion. Unless a scientist is willing to admit the issue has been politicized, and that cannabinoids are a known cure for many types of cancer, he/she is either ignorant or corrupt. Dangling a cancer treatment (before one has even been proposed/developed) is something a group of investors would do... and I imagine that is who wrote that article, some investors, thinking from an investor's angle. Good technology doesn't begin by putting out a random product into the population and THEN finding out what it's effects (positive and negative) are. That's something only a suicidal company (or one granted legal immunity) would do.
