Do you use cannabis to treat insomnia, sleep apnea, or other sleep disorders?
Do you have 15 minutes to answer some questions on your computer or mobile device?

Take part in a research survey about cannabis (i.e. marijuana/hash) use habits including mean of ingestion, strain, and concentration of cannabis components and self-reported sleep quality.

You will be adding to research in the field of cannabis, which aims to reduce associated harms while increasing benefits. By completing the survey, you will also be added to a drawing for an amazon gift card.

If you have used cannabis in the past 24 hours and would like to participate, follow the link here:
