Claim Raven explanation
What this means
For claims received after June 9, 1998, this rule generally bars service connection based on disease or injury attributable to tobacco use during service. It also describes situations where another basis for service connection remains possible.
A history of smoking does not automatically defeat every claim for a lung or heart condition. The question is the basis of the claim and whether the evidence supports a qualifying connection other than in-service tobacco use.
How this helps your claim
Check whether the decision actually evaluated the claimed service exposure, onset, or presumptive rule. Medical evidence should address the relevant causes honestly, including tobacco use where it matters.
What to check in your records
Use your decision, examination reports, and relevant records to check the following points.
- Confirm the date VA received the claim and the service-connection theory involved.
- Review medical opinions about tobacco use and other possible causes.
- Check whether VA considered an independently supported direct or presumptive connection.
Distinguish smoking history from the asserted cause
A respiratory or cardiovascular record may discuss smoking alongside other possible causes. The relevant question under this section is whether the claimed basis falls within the tobacco restriction or a permitted independent basis. The presence of a smoking history alone does not explain the entire decision.
Read any medical opinion for the relationship it actually addresses. An opinion about tobacco use may not answer a separate question concerning another documented event or exposure. Keep those theories distinct and supported by the record rather than assuming that changing the wording of a claim avoids the rule.
Does this rule bar every claim by a veteran who smoked?
No. It restricts specified tobacco-based claims and includes qualifications. A disability may require consideration under another supported basis for service connection. This page does not establish that another basis exists in an individual case; the actual medical and service evidence must support it.

eCFR snapshot: September 3, 2026. Layout and spacing are adapted for reading. The full section and its tables are included below.
§ 3.300 Claims based on the effects of tobacco products.
(a) For claims received by VA after June 9, 1998, a disability or death will not be considered service-connected on the basis that it resulted from injury or disease attributable to the veteran's use of tobacco products during service. For the purpose of this section, the term “tobacco products” means cigars, cigarettes, smokeless tobacco, pipe tobacco, and roll-your-own tobacco.
(b) The provisions of paragraph (a) of this section do not prohibit service connection if:
(1) The disability or death resulted from a disease or injury that is otherwise shown to have been incurred or aggravated during service. For purposes of this section, “otherwise shown” means that the disability or death can be service-connected on some basis other than the veteran's use of tobacco products during service, or that the disability became manifest or death occurred during service; or
(2) The disability or death resulted from a disease or injury that appeared to the required degree of disability within any applicable presumptive period under §§ 3.307, 3.309, 3.313, or 3.316; or
(3) Secondary service connection is established for ischemic heart disease or other cardiovascular disease under § 3.310(b).
(c) For claims for secondary service connection received by VA after June 9, 1998, a disability that is proximately due to or the result of an injury or disease previously service-connected on the basis that it is attributable to the veteran's use of tobacco products during service will not be service-connected under § 3.310(a).
