Armentano, Paul. "Marijuana Regulation Works and Prohibition Fails." US News.
U.S.News & World Report, 30 Oct. 2012. Web. 19 Oct. 2015.
Paul Armentano, the deputy director of the National Organization for the Reform of Marijuana Laws (NORML), is one of the most forging advocate for marijuana legalization in the United States. In his debate on US News, he argues that a national prohibition on marijuana is no longer effective but regulation and public education should be enforced because we are seeing increasing pot smokers in the US. He supports his argument by stating a study that proves the substance is actually less harmful than tobacco and alcohol. Armentano’s quotes appeared in both HCP and AP papers because his argument clearly states the worry of marijuana lealization and he suggests for a possible solution based on education.

Sullum, Jacob. "Does The First Amendment Protect Marijuana Ads?" Forbes. Forbes Magazine, 19 Feb. 2014. Web. 6 Oct. 2015.
This op-ed by Jacob Sullum falls right on my topic concerning the issue of advertising marijuana. The audience intends to be citizens of marijuana-legal states. Sullum is the author of two drug defense books which are Saying Yes: In Defense of Drug Use and For Your Own Good: The Anti-Smoking Crusade and the Tyranny of Public Health. Therefore, he holds authority in his op-ed on Forbes. The purpose of this editorial not only shares his opinion on the regulations of cannabis ads, but also conveys information about what the first amendment missed. He supported his opinion that restrictions on marijuana ads is difficult to guarantee through federal court by throwing several previous supreme court cases in his editorial. Although some of these cases are outdated, it is a fundamental evidence towards this 2014 editorial which reflects recent controversial. The source offers useful information on the current controversy of regulations on cannabis ads in Colorado.

The evidences that they use include opinions from other experts and survey from cannabis users. This is also a very recent research published in 2008. The source only tells the effects of marijuana, not much related to the main topic of this paper.
