It’s been two months since Colorado approved Amendment 64 – the legalization of marijuana for recreational use by adults – last November, and the city of Loveland, Colo. has had to deal with its fair share of incidents involving youth possession and distribution of the drug. But the latest is taking city officials by surprise: A middle school student is accused of bringing pot brownies to class, according to CBS 4 Denver.

During a city council meeting last week, Loveland’s police chief revealed that his department was investigating a case where a middle school student in the Thompson School District brought marijuana-laced brownies to class, reported the CBS affiliate.

According to the website of the local Reporter-Herald, Police Chief Luke Hecker refrained from commenting on the case, citing the ongoing investigation; the name of the student and the name of the school are being withheld.

The student involved is accused of sharing medical marijuana edibles with fellow students, according to ABC 7 News.

Amendment 64 leaves the enforcement of laws against the retail distribution of marijuana up to the discretion of local communities, and Hecker used the council meeting to urge that Loveland’s city counselors prohibit marijuana sales, the Reporter-Herald said.

The marijuana edibles the student allegedly brought to class were reportedly legally obtained, according to the Reporter-Herald. But while the new law legalizes the possession of up to 1 oz. of marijuana for people over 21 years old, cannabis remains illegal for anyone under 21 to possess or use. And no matter whether marijuana is intended for medical or recreational use, schools in the district remain drug-free zones.

A conviction for violating these drug-free rules could bring a minimum five-year jail sentence, according to CBS 4 Denver.

Thompson School District spokesman Michael Hausmann said he couldn’t disclose whether the student had been suspended because the district doesn’t comment on disciplinary procedures, reported ABC 7 News.

However, the “code of conduct” section of the district’s discipline code says that “Expulsion shall be mandatory for the distribution, trade, exchange, or sale of drugs or controlled substances, in accordance with state law.”

“The entire investigation was turned over immediately to the Loveland Police Department,” ABC 7 News reported Hausmann as saying. “We are awaiting the results of their investigation.”
