John Thune does not support decriminalizing marijuana at the federal level. He is aware that national perspective on marijuana is evolving.
Holds office U.S. Senate
"“Medical’s getting big — the recreational not as big yet, but it’s growing — and there’ll be more initiatives on the ballot. It’s an area that’s still evolving, and our country’s views on it are evolving… How we deal with it nationally I think is still an open question.” (06/27/21)
"While I understand that people have strong opinions on both sides of this debate, I do not support legalizing the use of marijuana. Currently, the medical benefits from the use of marijuana are still inconclusive, and I believe that we must be careful not to increase the availability of marijuana and the use of marijuana for nonmedical reasons. However, I support the development of alternative medications that will provide relief to patients without opening the door to substance abuse."

"We laugh about it and make jokes about where those brownies come from, but I think it's a dangerous path," said Thune on the legalization of marijuana. "They're going to pay a price for it in Colorado, and in fact, I think they already are."
