Yes, and in fact this is common. Those who have an addiction are also likely to have what are called “co-occurring disorders,” such as a mental health issue(s) like depression or anxiety.

Not every addict has multiple addictions or another psychological problem, but in general, there is a lot of overlap between these issues.
