According to the book "Women Under the Influence," which is an exhaustive 10-year analysis of substance abuse among girls and women, girls and young women are likelier than boys and young men to abuse substances in order to lose weight, relieve stress or boredom, improve their mood, reduce sexual inhibitions, self-medicate depression, and increase confidence.
Women in substance abuse treatment are more than five times likelier than men (69 percent vs. 12 percent) to have been sexually abused as children and girls and women are likelier than men to suffer eating disorders, both of which are major risk factors for substance abuse, CASA reports.
Women studied by CASA were more likely than men to say their heavy drinking followed a crisis, such as miscarriage, divorce, unemployment or recent departure of a child from the home.
Older women are likelier than older men to self-medicate with alcohol and prescription drugs in order to deal with loneliness, financial insecurity or loss of a spouse.
