Whether or not a suicide attempt results in death depends in large part on the method chosen. If a teenager attempts suicide with a gun, his or her death is nearly guaranteed. This brief fact sheet presents data on firearms and suicide, the third leading cause of death for adolescents and young adults in the United States. Any number of societal or personal factors could be causing more American youths to attempt suicide, but the use of guns makes these attempts successful. Statistics are given for the lethality of different suicide methods, and a comparison of the youth firearm suicide rate in an American city and a Canadian city with strict gun control laws. Finally, the impact of drinking on suicides among teenagers with access to firearms is touched on. (RB)
