Some studies have shown that cannaboids in marijuana do kill cancerous cells. When marijuana gets rescheduled to schedule 2, it will allow for a greater amount of research on this topic. So unfortunately for now, you are right, MJ can only mask side effects, but one day it potentially could be used to help fight cancer.
Watch the first youtube link obama wanted this guy to be surgeon general and he denied barack... He's on my side not yours so calm down and don't get upset at me i don't do drugs.. Marijuana is a plant that grows in the ground and it was a useful medicine for thousands of years before our new stupid WOD policy.. Also if you havent noticed in that time period cancer rates have exploded!! (Also thanks to processed foods and our environment)
Maybe you should blame your loved ones death on our stupid policies and not on me..
Heres a couple good documentaries if you feel like doing some real research instead of attacking me....
