How do I get these benefits?

You’ll need to file a claim for disability compensation.

You have to claim an actual disease or disability. It’s not enough to state that you were exposed to mustard gas or lewisite during service. You’ll need to apply based on the illnesses believed to be caused by your contact with one of these chemicals. When you send in your claim, be sure to share any military records that show you had contact with blistering agents.
