Marijuana through the lens of the New York Times

The legality of and public's view towards marijuana is rapidly changing as more states decriminalize and legalize the drug. As such, how have the words associated with marijuana in news articles changed over time? I developed a two-step approach to to try to answer this question. First, I wanted to identify distinct eras characterized by the use of key words associated with marijuana. Second, I aimed to assess whether words in each era represented larger themes regarding the public's view toards marijuana and the the drug's legality.
