One thought on “Drive safe for the New Year: a message from the CHP

  1. No one should drive impaired, but actual impairment should be measured, and the level of impairment from cannabis that is criminalized should be the same as the level of impairment for the .08 blood alcohol level. How to measure impairment? Read on!

    I have developed a new public health app that measures actual impairment–it is called DRUID (an acronym for “DRiving Under the Influence of Drugs”) available now in the App Store and in Google Play. DRUID measures reaction time, decision making, hand-eye coordination, time estimation and balance, and then statistically integrates hundreds of data points into an overall impairment score. DRUID takes just 2 minutes.

    Our website is http://www.druidapp.com

    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. Prior to DRUID, there was no way for an individual to accurately assess their own level of impairment. DRUID also demonstrates that it is feasible to measure impairment reliably by the roadside, not just exposure to a drug. It could also be a way for cannabis users who have developed tolerance to show they are unimpaired.

    DRUID was featured on NPR’s All Things Considered: http://www.npr.org/2017/01/25/511595978/can-sobriety-tests-weed-out-drivers-whove-smoked-too-much-weed

    Also on television: http://sacramento.cbslocal.com/2017/02/28/science-lags-behind-marijuana-impairment-testing/

    And this past December on Spokane Public Radio: http://nwpr.org/post/progress-made-marijuana-intoxication-measurement-tool-0

    NORML of California is promoting DRUID with a link to DRUID on their website, encouraging cannabis users to use it.

    After obtaining my Ph.D. at Harvard, I have been a professor of psychology at UMass/Boston for the past 40 years, specializing in research methods, measurement and statistics.
