Sulfur mustard
68 published decisions mention Sulfur mustard. Most of them are deciding other claims at the same time, so the table below is narrower on purpose: it counts only the 23 individual issues where the claim itself was tied to this exposure. This is a non-presumptive agent, the medical link must be proven case by case, so these Board rulings are the roadmap.
Note: Full-body mustard-gas testing has its own presumptive pathway; occupational exposure does not. Those may not require proving the medical link.
What the Board has tied to Sulfur mustard
Each row: a condition claimed as related to Sulfur mustard, how many issues the Board ruled on, and the granted / denied / remanded split. Click a condition to see its code page, criteria, and the decisions.
What these numbers count: 68 decisions MENTION Sulfur mustard; of the issues inside them, 23 were actually tied to this exposure, and 10 of those appear in the table. An issue the Board decided under two conditions appears in both rows, so the rows add up to 11. A further 10 conditions came up too few times to chart (fewer than 5 issues each, 13 issues in total) and are not listed, because a single case cannot show a pattern.
| Condition | Issues | Granted | Denied | Rem. | Grant % |
|---|---|---|---|---|---|
| Asthma, bronchial DC 6602 | 6 | 0 | 6 | 0 | – |
| Emphysema, pulmonary DC 6603 | 5 | 0 | 5 | 0 | – |

What the science says about Sulfur mustard
Sulfur mustard (mustard agent) is a blister agent. Some WWII-era service members were exposed in chemical-weapons testing; others through munitions handling. Exposure damages skin, eyes, and airways.
Health effects documented in the toxicology literature
- Respiratory: Chronic bronchitis, asthma, and other long-term airway disease after significant exposure.
- Eyes: Chronic eye problems and light sensitivity.
- Skin: Blistering injury; chronic skin conditions and scarring.
- Cancer: Associated with respiratory-tract cancers after heavy exposure.
Cancer classification: Sulfur mustard: IARC Group 1 (carcinogenic to humans).
Latency: Chronic effects and cancer can appear long after exposure.

Common questions
Is Sulfur mustard a presumptive exposure?
No. Unlike Agent Orange, burn pits, or Camp Lejeune, Sulfur mustard carries no automatic (presumptive) service connection. You have to prove the medical link yourself, usually with a nexus opinion, which is exactly why how the Board has ruled on it matters.
Why do so many of these conditions show denials?
The granted / denied counts reflect the mix of cases where Sulfur mustard comes up and how hard each link is to prove, not the merit of any one claim. A denial often means the file lacked a medical opinion tying the condition to the exposure, or proof of the exposure itself, not that the condition can never be connected.
How do I show I was exposed to Sulfur mustard?
Service records, your military job (MOS), unit history, and buddy statements can establish the exposure; a medical opinion then connects it to the diagnosed condition. This page reports Board outcomes and is not legal or medical advice, a VSO representative can help with your specific case.
