Smartphone Sensor Data Could Determine Cannabis Intoxication With 90 Percent Accuracy: Study 

A smartphone sensor, a lot on the traces of the GPS system, might assist decide if somebody is intoxicated after consuming marijuana, a brand new examine has demonstrated. The intoxication ensuing from the consumption of hashish is related to slowed response time, impact on work or faculty efficiency, and even influencing the driving behaviour usually leading to accidents and fatalities. 

The analysis, by Rutgers Institute for Well being, Well being Care Coverage and Ageing Analysis, was revealed within the Drug and Alcohol Dependence journal, and it assesses the feasibility of utilizing smartphone sensor information to determine hashish intoxication. Remarkably, the examine, which made use of a mixture of time options and sensor information, was discovered to be 90 % correct. That is vital, for the present strategies together with blood, urine, and saliva exams to detect hashish intoxication have limitations, specialists say.  

This is how they did it

Researchers evaluated each day information collected from younger adults utilizing hashish not less than twice each week. As a part of the examine, they analysed the cellphone surveys, self-initiated experiences of hashish use, and steady cellphone sensor information. 

In response to the evaluation, whereas the time of day and the day of the week had 60 % accuracy in detecting self-reporting of hashish intoxication, the mix of time options and smartphone sensor information may detect marijuana intoxication with 90 % accuracy. 

Tammy Chung, professor of psychiatry, mentioned that the cellphone’s sensors might assist us detect when an individual is experiencing hashish intoxication and ship a short intervention when and the place it may need essentially the most influence to scale back hurt.

In response to a press release, researchers used low burden strategies — monitoring time of day and day of the week and analysing cellphone sensor information — to detect intoxication in each day life. The examine demonstrated that the feasibility of utilizing cellphone sensors to detect subjective intoxication from hashish consumption was sturdy.
