Experts concur that urine, saliva and hair strand tests can ascertain if someone has used cannabis, but can take a long time to analyze because marijuana does not immediately show up in some bodily fluids.

They studied 33 adults who used cannabis at least twice a week and reported their use every day for up to 30 days.
During that period, volunteers wore an activity tracker to collect information on their heart rates, step counts and sleep quality. Sensors on the participants’ phones also provided information on their micromovements, such as how they held their phone and moved their arms, to gauge their stability and coordination, wrote New Science.
