Medical marijuana is marijuana that is prescribed by a doctor for the treatment of a health condition. For example, people who undergo chemotherapy will often be prescribed marijuana to stimulate their appetites and prevent excessive weight loss resulting from the side effects of chemotherapy treatment. Marijuana may also have some promise in the treatment of a variety of medical conditions (Mather, Rauwendaal, Moxham-Hall, &amp; Wodak, 2013; Robson, 2014; Schicho &amp; Storr, 2014).\r\n\r\n[caption id=\"\" align=\"alignright\" width=\"325\"]<img src=\"https:\/\/s3-us-west-2.amazonaws.com\/courses-images-archive-read-only\/wp-content\/uploads\/sites\/902\/2015\/02\/23224654\/CNX_Psych_04_05_Marijuana.jpg\" alt=\"A photograph shows a window with a neon sign.

There is quite a bit of controversy within the scientific community as to the extent to which marijuana might have medicinal benefits due to a lack of large-scale, controlled research (Bostwick, 2012). As a result, many scientists have urged the federal government to allow for relaxation of current marijuana laws and classifications in order to facilitate a more widespread study of the drug\u2019s effects (Aggarwal et al., 2009; Bostwick, 2012; Kogan &amp; Mechoulam, 2007).\r\n\r\nUntil recently, the United States Department of Justice routinely arrested people involved and seized marijuana used in medicinal settings.
