Critique the author's writing style in the article and express frustration about the lack of credible sources and analysis in the article.
This article is so poorly written.  First off, the only research cited stated that the amount of people using marijuana rose in the last 12 years.  Then it gave some "maybe, might be dangerous" stuff without citing any sources.  This is so irritating.  Either research the dang topic and share true information, or don't, but don't just write a freaking 2 page long article about crap.
