How are the study's sample sizes determined?

1. At a national level, the US Cannabis Product Brand Health survey has over 8,000 respondents and are larger than those carried out by large market research agencies and larger even than national presidential election polls (e.g. Ipsos, YouGov).

2. At a state level, our sample sizes are selected (using a well known statistical sampling method - Cochran's Formula) to provide a confidence interval of 95%, for a margin of error of 3%, taking into account the population of cannabis users in each state.

3. We are very proud of our sample sizes. With 18% incidence in the category and quarterly fielding, it is unlikely you will find a stronger study and more robust sample. If you do, please let us know, we aim to be the best on the market!
