Figure 4. Adjusted probabilities of having driven under the influence of cannabis (DUIC) on a certain number of days among those who gave a particular rating on the driving intoxication scale^a.

^aModel adjusted for number of days used cannabis in past 30 days, lifetime number of days used cannabis, years living in current U.S. state, age, gender, race, education, employment, sampling strategy and number of methods of administration used in one’s lifetime. Models estimated using cluster-robust standard errors to account for intrastate correlation. Limited to respondents who had used cannabis once or more the past 30 days and had driven under the influence of cannabis at least once in their life.
