There are many reasons but a few stand out.
Many people believe they can deal with their problem by themselves.
Others think that no one or anything can help them. A large percentage of people don't realize they have a problem because no one asks them how much they drink or if they take drugs. There are institutional policies and long-standing practices in place that discourage people from getting the help they need. Furthermore, there's an overall lack of understanding about what quality drug and alcohol treatment is. Too few consumers, family members and policymakers realize that drug and alcohol treatment is as effective as treatment for other chronic conditions like asthma and diabetes.
