Kansas state senator introduces medical marijuana bill TOPEKA, Kan. - A Kansas state senator has proposed a medical marijuana bill. Sen. David Haley, a Democrat from Kansas City, Kan., has introduced the bill, which would allow Kansas to join 18 states and the District of Columbia in allowing people to use marijuana with a doctor's order. The Topeka Capital-Journal reports the measure would allow patients to have up to six ounces of marijuana and grow up to a dozen plants at home. Sen. Mary Pilcher-Cook, chairwoman of the Senate Health and Welfare Committee, says the measure won't get a hearing during the current legislative session. Currently in Kansas, illegally obtaining marijuana for a health condition can mean a year in jail, and growing your own pot can mean up to 17 years in prison.
