For Canada in particular, I am not. A recent Canadian Medical Association Journal article came out showing that while firearm suicides do seem to go down in association with gun legislation, overall suicide stays the same. They ranked my studies, actually, as the highest-ranking studies within their review.
Other studies from Australia have also shown that while firearm suicide rates may decrease, overall suicide rates don't change. There are multiple studies involved and I have submitted those in my brief to this committee.
On the ease and ability for hanging, hanging is 80% effective for suicide, which is similar to firearms. When someone has serious intent, it's almost impossible to deter them. Unfortunately, as physicians we have no clinical decision rules or ability to really predict who's going to commit suicide.
When I see a patient and they own firearms, we discuss risk reduction. That means the CFO removes the firearms or they give them to their friends. The second thing I can give them is a referral to psychiatry for about eight months later. That's almost an insult.
