The Index of Cannabis Equivalence (ICE): A User-Centered Approach to Standardization of Cannabis Dose-Response.

The increasing acceptance of cannabis use, and policy changes in several jurisdictions has led researchers and public health experts to call for a standard cannabis dose.

Efforts to standardize cannabis dose have focused on cannabinoid content without considering tolerance or mode.
