A protest was held outside Toronto police headquarters Sunday afternoon by dozens of pot enthusiasts who claim officers used excessive force during a recent drug raid at a downtown medical marijuana club.

The raid took place last Wednesday at the facility known as the "calm club," located on Queen Street near Jarvis Street.

Police say the facility does not hold a Health Canada license, as is required. Authorities say they seized 16 kilograms of marijuana during the raid, which is worth about $160,000 on the street.

But one demonstrator said that people who use the club are licensed to smoke pot to deal with their medical conditions.

A lawyer representing the Calm Club says he is asking police to return the drugs to these licenced users.

The owner of the Calm Club and eight employees have been charged in connection with the raid.

Complaints from the community are what led to the raid, police said.
