I did watch it, it's about the oil, but your average stoner "HURR POT CURES CANCER MAN *toke toke*". They'll claim day in and day out about the benefits, but then won't say "the benefits only work in extract form", or they don't care and just want to use it as an excuse to smoke up. Look at the thread title, it's sensationalist. It doesn't say that the oil with the extract can help it, it just says "Marijuana is a cure to cancer!". Stoner mentality of "pot is great, see this is why you legalize it man! *smoke*"
No, you legalize it because it's not a government's position to tell me what I can or can not put in my body. Go smoke meth, I don't care as long as you aren't neglecting your kids as a result. Kill yourself if you want, not my concern.
