9. Substance abuse

This is one of the most common consequences of depression, especially in men. Substance abuse is associated with clinical depression, and it is usually around alcohol, but may also include illegal drugs and some prescription drugs these patients find illegally. They use these substances, and often food as well, as a means to cope with depression and momentarily feel better. This one is not included in the diagnostic criteria, but substance abuse is responsible for making the symptoms of depression even worse.
Patients with depression and substance abuse are more susceptible to feeling worthless and sad when they are off the effects of alcohol and drugs. They are usually more aggressive and impulsive, and their social, academic, and working skills become even more impaired. Thus, it is important to address this issue before it becomes an additional problem for the patient and his family.
