Bias and Beffuddlement: Our Government's Approach to Marijuana Facts and Research

So I was trying to find out our government's exact justification for making marijuana illegal. The first website I went to was the The Office of National Drug Control Policy. Unsurprisingly, the section on health effects is completely biased. There is a part where it claims that marijuana can cause lung cancer, citing the National Institute of Drug Abuse. I went over to their website, and they describe a recent study that claims that there is no connection between marijuana use and lung cancer! This is just one example of how the federal government is deliberately dishonest about marijuana and its effects.
