MADISON, Minn. (AP) — A group advocating medical marijuana is delivering a petition to the Lac qui Parle County attorney asking him to drop charges against a woman charged after giving her son cannabis oil for his pain.

Minnesotans for Compassionate Care says it’s has collected nearly 9,000 signatures in support of Angela Brown, who has been charged with child endangerment. Her 15-year-old son suffers from a traumatic brain injury.

Gov. Mark Dayton signed Minnesota’s medical marijuana law in May, but it doesn’t go into effect until next July. The organization’s Patrick McClellan says charges against Brown are unnecessary and unreasonable.
