FAQ's About The DruidApp and Impairment Science Inc.

Most frequent questions and answers

The DRUID® app has been available since 2016, and there have been over 17,000 downloads. The Enterprise version is newly released, but the test is the same as the personal test that has been scientifically validated and calibrated.

The app is free for personal use for 30 days, then $1.99 per month or $14.99 for a year’s subscription.

The Price for an Enterprise version is based on the number of users/tests and type of installation. 

About 12 minutes to learn the app in order to get an accurate score, and then 3 minutes for each test thereafter.

The app was initially developed to be used as a tool to assess whether an individual possessed the minimum cognitive and motor capabilities required to drive a vehicle. These capabilities are:

  1.  Reaction times
  2.  Balance
  3.  Performance of tasks while distracted.

DRUID is a mobile app; it is compatible with most iOS and Android phones and tablets.

Yes, we have an Enterprise version which provides administrative capabilities, workflow integration and some customization.

The accuracy of app is calibrated to impairment levels found with a .08% alcohol blood level and with the Standard Field Sobriety Test. We anticipate working with law enforcement soon; this should help establish legal precedent for using DRUID in a law enforcement setting.

No. DRUID tests only if someone is impaired in certain capabilities, such as reaction time, performing divided attention tasks, balance, – capabilities that, if impaired, can make driving, operating heavy machinery, and other activities dangerous to themselves or others.

The DRUID app has been tested for accuracy and calibrated to standards for impairment associated with measured levels of blood alcohol.   Researchers around the world are using DRUID as a quick and accurate impairment testing device.  Research conducted by Dr. Ryan Vandrey at Johns Hopkins School of Medicine found that the DRUID app is sensitive enough to distinguish different levels of impairment from different amounts of THC that a person ingests.  He has recently submitted a research paper for peer review, confirming the accuracy and sensitivity of the app.

Since DRUID is a neuro-psychological measure of impairment with no biologicals tested, DRUID identifies impairment from alcohol as well as from cannabis.  Published peer-reviewed validation of DRUID as a test for alcohol impairment (Richman & May, 2019) is here: http://pubs.covd.org/VDR/issue5-1/index.html

No. The DRUID test, can find impairment for many reasons; for example, from fatigue, side effects of prescribed medications, recent trauma, or illness.

False Positive tests can occur for a number of reasons. If you receive a high score on your first few tests, you may not have practiced enough to be proficient. You may need to practice a couple more times to establish a normal unimpaired score.  Other reasons for a false positive may include being distracted or interrupted during a test, being jostled or interrupted during the balance portion of the test, or just not paying attention.  If a score is believed to be a false positive, simply take the test again. Make sure that you are paying attention and not interrupted or distracted.  If the score is still high, then it is likely that you are impaired. Your impairment may be due to use of drugs, legal or illegal, alcohol, fatigue, injury, or illness.

False Negatives result from cheating on the test.  We are implementing a variety of measures to ensure that a person is taking the test as intended.  The app will identify if the tasks are not being performed with attention and as required. If this happens, the app will either suggest that the person retake a portion of the test or will stop the test entirely and the person can take it again from the beginning. For the near term, if an employer utilizing the Enterprise version is worried about cheating, test taking should be supervised.

 

 

DRUID is a tool like any other and should be used as part of an overall employee safety program.  Failing a DRUID test may mean that a person is not fit for duty:  that their motor control and decision-making may be compromised; that they should not, for instance, operate a vehicle or machinery, scale ladders, or perform surgery.  Failure may mean that the person is fatigued, taking a new medication, injured, or ill. It does not necessarily mean they are intoxicated.  It means that the person should not perform dangerous activities at that time. What action, if any, should be taken by an employer should be consistent with company policies already in place. The DRUID app provides information to help individuals and organizations to make intelligent decisions.
