Cannabis Research Index

Countries And States Ranked By The Number Of Clinical Studies

We have found and analyzed a total of 508 clinical studies, reported to ClinicalTrials.gov, that research cannabis and cannabis-derived medications. That allowed us to build first of its kind Cannabis Research Index that ranks countries and states by the number of clinical cannabis research studies.

This index does not account whether research is funded at the government level or by private enterprise; it also does not consider the amount of funding received. With this being said, the index explores a single aspect of overall cannabis research, so treat it as such.
