In the Diagnostic and Statistical Manual of Mental Disorders, Fifth Edition, known as the DSM-5, a distinction is no longer made between substance abuse and substance dependence. Moreover, the term “substance abuse” is no longer used.  The term now used is Substance Use Disorders, or SUDs. 

SUDs can include problems with a variety of substances including alcohol, cannabis, opioids, stimulants, and hallucinogens.  A disorder occurs when the recurrent use of substances leads to clinically and functionally significant impairment, such as health problems, disability, and failure to meet major responsibilities at work, school, or home.
