A new Harris Poll conducted for Royal Queen Seeds (RQS) finds 61% of U.S. adults support legalizing home marijuana cultivation—a figure exceeding the 43% of Americans who say they have used cannabis, showing that support extends well beyond current consumers.
Pesticide concerns are central: 72% of cannabis consumers are very worried about harmful chemicals in their products, and 65% say media coverage of contaminated cannabis has made them more inclined to grow their own rather than buy. Two-thirds of consumers (67%) would choose pesticide-free cannabis over higher-THC products that used agrochemicals.
"Consumers today are more informed and more intentional about what they put into their bodies," said Shai Ramsahai, president of RQS. "Blindly buying products just because of a high THC percentage is a fading trend. People want cannabis they can trust, and many are turning to home cultivation to take control over quality and safety."
Among other findings, 76% of cannabis consumers prefer the marijuana "high" to an alcohol "buzz," 39% of all Americans (and 68% of cannabis users) would find home-grown marijuana more impressive than expensive wine at a dinner party, and 80% of consumers connect their cannabis use to broader wellness habits.
The poll drew on interviews conducted March 17–19 with 2,017 U.S. adults aged 21 and older, including 851 cannabis consumers, with a margin of error of ±2.7 percentage points.
This is the latest in a series of RQS polls. A prior RQS survey found that half of U.S. marijuana consumers expected to increase their cannabis use under the Trump administration; a 2024 RQS poll found 37% of respondents would consider buying cannabis seeds as a 4/20 gift for someone else.
Separately, a Gallup poll found 64% of Americans support marijuana legalization. Gallup's 2024 data showed 15% of U.S. adults smoke cannabis versus 11% who reported smoking cigarettes in the past week. A separate Gallup survey found use rates are nearly identical in legal and prohibition states, with the data suggesting "criminalization does little to curtail its use."
