College Gun Owners Prone to Bad Behavior College students who own guns have lower grades than their peers and are more likely to drink excessively, vandalize property and get into trouble with police more often than students who do not own firearms, according to a Harvard study.

Recently published in the Journal of American College of Health, the study, titled, "Guns and Gun Threats at College," shows an association of firearm owners to risky behaviors, but does not list the cause for the action.
