Past Use vs. Current Substance Use Disorder

There is an important legal distinction between past drug use and a current substance use disorder. Under U.S. immigration law, drug abuse or addiction is a ground of inadmissibility. However, this refers to a current clinical diagnosis of a substance use disorder — not to past experimentation, recreational use, or a history of use that has since resolved.

What USCIS Screens For

The immigration medical examination includes a substance use screening. The civil surgeon will ask about your history of drug and alcohol use and will evaluate whether you currently meet the clinical criteria for a substance use disorder as defined by the Diagnostic and Statistical Manual of Mental Disorders (DSM).

The civil surgeon is not making a determination based on whether you have ever used drugs. The evaluation is focused on your current status and whether there is evidence of a current disorder.

How the Civil Surgeon Evaluates Substance Use

The civil surgeon will conduct a clinical interview and review your medical history. If there is evidence of a current substance use disorder — such as ongoing use, inability to control use, or significant impairment in daily functioning — the civil surgeon will document this on Form I-693. If you have a history of past use that has resolved, and you do not currently meet the criteria for a substance use disorder, this will generally not be a finding of inadmissibility.

When Past Use Becomes a Concern

Past drug use can become a concern in the immigration context if it is recent, if there is evidence that it has not fully resolved, or if it is associated with other legal or behavioral issues. If you have completed a substance use treatment program, bringing documentation of your treatment and recovery can be helpful.
