Researchers have shown preliminary grounds that is potential to betoken if someone is high on hemp using smartphone sensors . The approach uses some datum from the owner ’s smartphone to judge if they have become drunk after consuming cannabis .
The work is published in the journalDrug and Alcohol Dependenceand it is based on a survey of 57 young adult aged between 18 and 25 in Pittsburgh , Pennsylvania . The player self - report using cannabis at least double per week , and the team used data from their nomadic phones to see if this was enough to operate out when citizenry consumed the nub .
The accelerometer – the move sensor within the phone – and GPS data point were of import features in find intoxication . Using just time characteristic , such as twenty-four hour period of the hebdomad and time of the mean solar day , the study was able to correctly identify 60 percentage of the 451 cannabis use episode . The accuracy mount to 90 percentage once meter feature of speech , combined with smartphone sensor datum , were included in the analysis .
" Using the sensor in a person ’s phone , we might be able to detect when a individual might be experiencing cannabis intoxication and bear a brief intervention when and where it might have the most impact to reduce cannabis - related harm , " corresponding author professor Tammy Chung , from the Rutgers Institute for Health , Health Care Policy and Aging Research , said in astatement .
The glide path is still a proof of conception but it does suggest that it is in principle practicable to use a phone sensor to notice cannabis drunkenness , in a way that could be used for deliveringtimely interference . It is get it on that smart technology can be little stoolpigeon if you let them , recording your localisation and activities . And it looks like raw enough to actually determine some unusual behavior .
Smartphones have antecedently been used ina standardized approachwhen it comes to drunkness . Although that trial was lead in the research laboratory and not a more natural environs , the accelerometer was still able-bodied to pick up when a someone had squander alcohol over the sound driving limit in the United States about 90 percentage of the sentence .
In the US , hemp is illegal under Union law , although the medicinal usance of cannabis has been legalize in 36 land , four out of five for good inhabited U.S. territories , and Washinton DC .
