In general, if a person is sacrificing things that they enjoy in order to use a substance, there is a problem. For someone with an active social life this can be an important sign to look out for, even if that person brushes off their diminishing hangouts. "There are plenty of people who don't admit it themselves, but it's painfully apparent to everybody around them," says Compton. If someone you're close to needs a wake-up call about their substance use but doesn't want others involved, you can encourage them to look at drug and alcohol screening tests on their own.
