Well actually "Kiffen gegen Schmerzen" is the name of a very informative Die Zeit article on California's medical marijuana law, although the article also notes that "Kiffen gegen die Staatskrise" may be equally applicable as the State of California receives over $1 billion dollars annually in tax revenue from the sale of medical pot. But I digress.
Students in any of my courses where we have discussed the American version of federalism should immediately know why this law is of interest to us. Students currently in my American Constitutional Law course will learn why next week. Either way, anyone interested in learning more about California's somewhat controversial law should take a look at the article in Die Zeit.
