14,256 rated or chosen profiles from 891 respondents, in up to 8 tasks of 2 profiles varying on 7 attributes.
| Description | Canadian adults who had bought cannabis in the past year (Angus Reid online panel, October 2021; 891 respondents) chose between two hypothetical dried flower cannabis products (price, packaging, moisture, potency, recommendation source, package information, Health Canada regulation) in 8 forced-choice tasks; one of four DCEs in the same survey. |

Because the attribute levels were not randomized independently, an estimator has to account for the restriction; a plain difference in means across levels can mislead.
