Michigan Compiled Laws, Chapter 333. Health § 333.26422

(a) Modern medical research, including as found by the National Academy of Sciences' Institute of Medicine in a March 1999 report, has discovered beneficial uses for marihuana in treating or alleviating the pain, nausea, and other symptoms associated with a variety of debilitating medical conditions.

(b) Data from the Federal Bureau of Investigation Uniform Crime Reports and the Compendium of Federal Justice Statistics show that approximately 99 out of every 100 marihuana arrests in the United States are made under state law, rather than under federal law. Consequently, changing state law will have the practical effect of protecting from arrest the vast majority of seriously ill people who have a medical need to use marihuana.

(c) Although federal law currently prohibits any use of marihuana except under very limited circumstances, states are not required to enforce federal law or prosecute people for engaging in activities prohibited by federal law. The laws of Alaska, California, Colorado, Hawaii, Maine, Montana, Nevada, New Mexico, Oregon, Vermont, Rhode Island, and Washington do not penalize the medical use and cultivation of marihuana. Michigan joins in this effort for the health and welfare of its citizens.
