CSC seize packages of contraband at Joyceville Institution

Packages containing contraband have been seized at Joyceville Institution, a multi-security prison in Kingston’s east end.
According to Correctional Service Canada (CSC), the seizure was “the result of the vigilance of staff members,” and was made on Monday, Jan. 24, 2022, during a routine search of incoming property
The contraband seized included 19 grams of shatter (cannabis concentrate), according to a release from the CSC, dated Wednesday, Jan. 26, 2022.
In the release, CSC said that the organization uses a number of tools to prevent drugs from entering its institutions. These tools include ion scanners and detector dogs to search buildings, personal property, inmates and visitors.
“The Correctional Service of Canada has measures in place to prevent contraband and unauthorized items from entering its institutions in order to help ensure a safe and secure environment for everyone,” the national correctional authority said. “CSC also works in partnership with the police to take action against those who attempt to introduce contraband and/or unauthorized items into correctional institutions.”
Anyone with information relating to security at CSC institutions, including drug use or trafficking which may threaten the safety and security of visitors, inmates, and staff at CSC institutions can share that information anonymously by calling 1-866-780-3784, toll-free.
Since cannabis is legal now, what does this seizure mean? Can prisoners avail themselves of cannabis in a more transparent/acceptable way?
