David Phillip Roe (born July 21, 1945) is an American politician and doctor who is the U.S. Representative for Tennessee's 1st congressional district, serving since 2009. He is a member of the Republican Party. The district is based in the Tri-Cities area in the northeastern portion of the state. In 2017, Roe became chairman of the House Committee on Veterans Affairs.

"As a physician, I am keenly aware of the need to look for opioid alternatives to treat patients' chronic pain," Roe said Tuesday in a written statement. "Since serving as chairman of the House Committee on Veterans' Affairs, I've heard from many veterans, both with physical and invisible wounds, who believe medical cannabis could benefit them."

"Until we have sound science behind whether or not medical cannabis is an effective treatment, we should not move forward with prescribing it," he said.

"It's very simple. (Marijuana is) a drug. That drug should be studied, like any other drug. Legislatures shouldn't be deciding whether it's applicable or not. Scientists should be. ... �I feel good' is not science."
