GARDEN CITY, Kan. (AP) — A western Kansas woman has pleaded not guilty to charges stemming from accusations that arose after 11-year-old son said in school that his mother smokes marijuana “a lot.”

Shona Banda pleaded not guilty Monday to three felonies and two misdemeanors relating to marijuana use.

Ms Banda’s preliminary hearing is Nov. 16.

Law enforcement and Kansas Department of Children and Families officials started investigating Banda after her 11-year old son said “my mom smokes … a lot!” during an anti-drug program at a Garden City school.

Banda is the author of a book recounting her use of concentrated cannabis oil to treat Crohn’s Disease.
