The World Wide Weed research team (a.k.a. the Global Cannabis Cultivation Research Consortium, or GCCRC) welcomes you to our international project website.
We are a group of researchers interested in better understanding domestic cannabis cultivation, especially by small-scale growers. We want to better understand who grows cannabis, reasons for growing, methods of growing, and experience with the criminal justice system – and how these factors differ across national borders.
In 2012-2013 we conducted the first global survey of cannabis cultivators. Thank you to the thousands of growers who participated. Outputs from that survey can be found in a special issue of the International Journal of Drug Policy and more are listed in our publications list.
Our follow-up global survey of cannabis cultivators is due to launch in August 2020. Please check your country below to participate when the survey goes live!
