As we know, there is a distinctive pattern of use for those addicted to most substances, however, there is different criteria for diagnosing specific substance use disorders (i.e. opioid use disorder, alcohol use disorder, methamphetamine use disorder, etc.). Substance use disorders can be at varying levels of severity, for different lengths of time; it is not likely for all substance users to score similarly against the criteria for a substance use disorder.
Level of Substance Use Disorder Severity: the more symptoms that apply, the more severe the substance use disorder is.
2 or more symptoms = mild substance use disorder
5-7 symptoms = moderate substance use disorder
8+ symptoms = severe substance use disorder
