It's not true, marijuana was genetically engineered by the government to control the lower class.
Honestly though, no one is shocked that the majority of social media users are shallow and lack the desire/ability to think critically. Thats all the things that facebook, etc., is known for. I especially giggle at the findings about users reposting stories to reinforce an image of themselves, while not actually reading content; it's just so perfect. If that doesn't define shallowness, I don't know what does.
Whoa, I needed some serious smartphone spelling correction.
