Though the Interagency Grizzly Bear Committee, created in 1983 to lead the recovery of the grizzly bear in the lower 48 states, does not endorse any particular commercial bear spray, it points out in its literature that proper use of bear spray can:
- reduce the number of grizzly bears killed in self-defense,
- reduce human injuries caused by bears, and
- help promote the recovery and survival of the grizzly bear.
In a study in the April 2008 edition of the Journal of Wildlife Management, Tom Smith examines "The Efficacy of Bear Deterrent Spray in Alaska." The study shows that in 72 cases where people use bear spray to defend themselves from brown, black and polar bear the spray stopped brown bears 92 percent of the time and 98 percent of the people involved were uninjured.
