The Saskatchewan Compassion Club has been raided by Saskatoon police and four people are facing charges including trafficking marijuana.
The club, which opened up in August, is designed to help people gain access to medical marijuana more easily.
Saskatoon police had previously warned founder Mark Hauk that the club would be closed down if it was found to be breaking the law.
Health Canada had also warned the dispensary that if it did not cease and desist activity, it would refer the file to the RCMP.
Police said two Saskatoon men, ages 24 and 36, and two Saskatoon women, ages 23 and 39, were arrested on Thursday. Their identities were not released.
