The survey was administered between 27 September and 9 October 2017. The response rate was determined by using methods outlined by the American Association for Public Opinion Research and was the ratio between respondents and all survey recipients. All analyses used weighting commands using the variable provided by GfK to generate national estimates. Respondents were asked about form of marijuana use with the following question: “In what forms have you used marijuana in the last year? Select all that apply.” Response options were as follows: smoking, vaping, edibles, concentrate, and topically.
