BOWBELLS, N.D. — Grammy-winning rock singer Melissa Etheridge has pleaded guilty to a misdemeanor charge of possessing marijuana in North Dakota.

KMOT-TV reported that an attorney for the California musician entered the plea on her behalf Tuesday. Under a proposed order, Etheridge would pay a fine of $750 and serve unsupervised probation.

Etheridge was arrested in August when investigators found marijuana on her tour bus as it crossed from Canada into the U.S. Etheridge, who is a cancer survivor, has said she believes in the medicinal applications of cannabis.
