Illegal drugs are a major public health concern and social problem. In addition to personal harm and health problems, drug use can have criminal and financial consequences. If these feelings pass in a few days, or even a few weeks, then depression is not a major problem. This is true even if the individual sought short term therapy to get over the rough spot. If an episode does not pass, is more severe then usual, or seems to be getting worse, more intensive therapy or anti-depressant drugs may be needed.
Depression can occur at any age.
It is not always easy to detect. The outward signs may be nothing more than an unusual quiet. Most people suffering from depression have feelings of hopelessness and despair. The extreme end of depression is suicide. All talk of suicide should be taken seriously.
