A marijuana use or cannabis use disorder diagnosis in your VA treatment records does not automatically disqualify you from disability compensation, but it can complicate how a claim is evaluated, and the effect depends heavily on the specific condition being claimed and how the diagnosis is documented.
VA disability ratings are governed by 38 CFR Part 4, and substance use disorders are generally rated only when they are shown to be secondary to a service-connected condition, most often PTSD, depression, anxiety, or chronic pain (38 CFR 3.310 covers secondary service connection). Under 38 USC 105 and 38 CFR 3.301, VA can deny direct service connection for a disability resulting from a veteran's own willful misconduct, and illegal drug use is treated as willful misconduct for that limited purpose. This generally matters for claims trying to connect a disability directly to drug use itself, not for separate, independently diagnosed conditions that merely coexist with documented marijuana use in the record.

Examiners sometimes attribute symptoms like poor concentration, sleep disruption, or mood changes to cannabis use rather than to PTSD or another service-connected condition, which can lower a rating or support a lower disability percentage than the underlying condition would otherwise warrant. This is an evidentiary and medical-opinion problem more than a strict legal bar, and it can often be addressed with a strong nexus opinion from a treating provider that separates symptoms caused by the service-connected condition from any substance use.
Because marijuana remains a Schedule I substance federally, VA providers cannot prescribe it or formally endorse its use, and this sometimes shapes how diagnoses are written in a way that looks more negative on paper than the clinical reality. It does not, however, change the basic rule that VA must rate you based on the actual current severity of your service-connected condition, factoring out nonservice-connected substance use where medically distinguishable under 38 CFR 4.14 and related adjudication guidance.
If you are concerned that a marijuana-related diagnosis is affecting your claim or rating, request your complete C-file and C&P exam report, have a treating mental health provider submit a detailed opinion separating your service-connected symptoms from any substance use, and work with an accredited Veterans Service Officer before filing a Supplemental Claim (VA Form 20-0995) with that new medical evidence.
