The Druid App was developed by Professor Michael Milburn at UMass/Boston. DRUID allows cannabis users (or others who drink alcohol, use prescription drugs, etc.) to self-assess their own level of impairment and (hopefully) decide against driving if they are impaired.

California NORML is promoting DRUID on their website, and has been featured:
On NPR’s All Things Considered: www.npr.org/2017/01/25/511595978/can-sobriety-tests-weed-out-drivers-whove-smoked-too-much-weed

On television: sacramento.cbslocal.com/2017/02/28/science-lags-behind-marijuana-impairment-testing/
On Spokane Public Radio: nwpr.org/post/progress-made-marijuana-intoxication-measurement-tool-0

NORML Canada members are encouraged to download and use the app as a potential tool to minimizing the concerns about impaired driving once cannabis is legal, and today.
