A woman with a lead foot who apparently enjoys her marijuana will serve three months in jail.The woman, Kimberly Lynn Cantrell, 46, entered guilty pleas to two separate marijuana charges along with a charge of driving on a suspended license. Circuit Court Judge Bart Stanley directed she serve 30 days on one count and 60 days on the second count, combining for a total 90 days of incarceration at the county jail.She will also be on probation for three years and must pay $2,750 plus court costs and perform 48 hours public service work. She will be required to undergo drug and alcohol counseling.Her jail time comes for a pair of speeding stops which both ended in her being charged with possession of marijuana.The first happened back in September 2011 when state trooper Donnie Clark clocked her doing 70 mph in a 55 mph zone on West Green Hill Road.
