There have been similar campaigns in the past. Most notably, there was a one-day medication return that was led by the pharmacists association and also by the police chiefs. We also found that a lot of Canadians keep their medications at home for long periods of time. People don't necessarily think to clean out medication cabinets when their family members pass away, and there have been some very unfortunate situations where people have broken into their homes.
A large part of this campaign is going to be about stressing the importance of returning medications on a regular basis, as opposed to holding on to them and disposing of them once a year, if that.
