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. And it is common for people to have more than one substance or process/behavior addiction. Research clearly links substance use to problems with gambling, video gaming, disordered eating, Internet use and compulsive sexual behavior. Not everyone with a substance use disorder has multiple addictions or another psychological problem, but in general, there is a lot of overlap between these issues.
