Agent Orange and other herbicides were used extensively during the Vietnam War, not only in Vietnam but also in neighboring countries, including Laos. The impact of these chemicals on veterans and their families has been profound, leading to numerous health issues and a long struggle for recognition and benefits.
The Use of Herbicides in Laos
During the Vietnam War, the U.S. military conducted secret operations in Laos, including the spraying of herbicides such as Agent Orange, Agent White, Agent Blue, and Agent Purple. From 1965 to 1971, herbicides were sprayed over Laos, particularly along the Ho Chi Minh Trail. Spraying was focused on the border regions near Vietnam, where the Ho Chi Minh Trail crossed into Laos and Cambodia. Thousands of gallons of herbicides were used in these operations.
Limited testing has confirmed the presence of dioxin, the toxic component of Agent Orange. In 2005, elevated levels were found at the former Chavan airbase, suggesting other areas might also be contaminated.
Presumptive Service Connection
The Honoring Our PACT Act, signed into law in 2022, has expanded the benefits available to veterans exposed to toxic substances, including those who served in Laos. This landmark legislation provides presumptive service connection for various conditions associated with herbicide exposure, making it easier for veterans to receive the benefits they deserve.
Who Qualifies for the Agent Orange Presumption?
Under the PACT Act, the VA presumes herbicide exposure for veterans who served in any capacity in areas of Laos where herbicides were likely used, between December 1, 1965 and September 30, 1969.
Current presumptive conditions related to Agent Orange and herbicide exposure include hypertension, ischemic heart disease, diabetes, chloracne, Parkinson’s, hypothyroidism, MGUS and multiple types of cancer. Find them all here.
What If I Served Outside the Recognized Timeframe or Area?
If your service in Laos falls outside of December 1965 – September 1969, or cannot be directly linked to the spray zones, you may still pursue direct service connection. In this case, you’ll need credible evidence of Agent Orange or herbicide exposure and a medical opinion linking your diagnosis to that exposure.
This process requires more evidence but remains a valid and potentially successful path to compensation. Our VA-accredited disability lawyers understand the complexities of herbicide claims and may be able to help you win the appeal if the VA has denied your rightful benefits.
VA Benefits Available to Laos Veterans and Their Families
Veterans who qualify for Agent Orange or herbicide exposure and have a related diagnosis may be eligible for a range of benefits, including:
- Disability Compensation: Monthly tax-free payments based on the severity of the condition.
- Healthcare Services: Access to VA medical services and specialists.
- Dependency and Indemnity Compensation (DIC): Monthly payments to surviving spouses and dependents.
- Education and Training: Programs to support the education and training of veterans and their families.
How to File for Benefits
- Gather Documentation: Obtain military service records showing duty in Laos during the qualifying dates and collect medical records for your diagnosed condition
- Submit a Claim: File online through VA.gov, by mail, or with help from an accredited VSO or legal representative.
- Wait for VA Review: The VA will evaluate the claim and may schedule medical exams or request additional documents.
- Receive a Decision: Once reviewed, the VA will issue a written decision detailing your eligibility and benefit level. If denied, the veteran has the right to appeal. (For appeals, we recommend seeking assistance from an Agent Orange lawyer.)
