The National Advanced Driving Simulator (NADS) at The University of Iowa Research Park invites adults to participate in a study looking at both perceptions about cannabis use and driving and the effects of cannabis use on driving performance. The link below will take you to a survey that has information about the perception questionnaire as well as information about the driving simulator study conducted on the NADS minSim, a non-motion driving simulator. If you indicate interest in the driving simulator study, you will be directed to an eligibility questionnaire for the study. You may choose to complete only the questionnaire, complete only the eligibility questionnaire for the driving simulation study, or to complete both parts. Compensation is up to $385 for your time and effort in the driving simulation study. There is no compensation for completing the questionnaire, but your responses will be used to evaluate cannabis use and perceptions of cannabis use in our area. If you are interested in participating, please visit the following link for more information and to complete the online questionnaire(s): https://redcap.icts.uiowa.edu/redcap/surveys/?s=W3EL8M7NKT
