When a C&P examiner attributes a psychiatric condition to a substance use disorder they say pre-existed service, the first thing to check is the presumption of soundness under 38 U.S.C. § 1111 and 38 C.F.R. § 3.304(b). If a condition was not noted on your entrance examination, you are presumed to have entered service in sound condition. The VA can only rebut that presumption with clear and unmistakable evidence both that the condition pre-existed service and that it was not aggravated by service. A C&P examiner's opinion alone, especially one built on an inaccurate factual premise (like a pre-service diagnosis that isn't supported by your entrance records), generally does not meet that high "clear and unmistakable" standard.
Because the factual basis of the opinion appears to be wrong, you have two overlapping paths. One is to challenge the accuracy of the exam directly, showing that your service treatment records, entrance exam, and personnel file contain no evidence of pre-service cannabis use or diagnosis. The other is to obtain an Independent Medical Opinion (IMO) or nexus letter from a private psychiatrist or psychologist who can review the full record, address the presumption of soundness, and explain why the in-service or post-service diagnosis is more consistent with either direct service incurrence or aggravation of a condition, if one is found to have pre-existed after all. A strong nexus letter should cite the DBQ criteria, discuss the rebuttal standard, and directly rebut the examiner's reasoning point by point.

If you plan to submit a new IMO/nexus letter or updated records, a Supplemental Claim (VA Form 20-0995) is the correct vehicle, since it requires new and relevant evidence. Some veterans pursue both in sequence: first an HLR to challenge the legal reasoning, then a Supplemental Claim with new medical evidence if the HLR is denied.
Among appealed service-connection decisions in VetAid's library, appellate outcomes vary considerably, with a substantial share remanded for further development and a smaller share reversed outright — though these are outcomes from cases that already went through appeal, not odds for an initial claim.
The concrete next step is to request your complete claims file (C-file) to confirm exactly what evidence the examiner relied on, then get a private nexus opinion that directly addresses the presumption-of-soundness standard before deciding between an HLR and a Supplemental Claim.
