In the United States, Colorado was the first state to legalize marijuana with Washington and Oregon following close behind. The percentage of car accidents signifcantly increased after marijuana was legalized for a longer period of time. Therefore, there is a need for a roadside diagnostic device to prevent these statistics from rising, just as there has been a need to regulate legal alcohol consumption with breathalyzer tests. Currently, cops do not have a gold standard for testing drivers for marijuana usage. Their current methods include a standard Field Sobriety Test to see if someone is impaired. If the person fails, the police arrest the person and bring them into the station to do further testing. Because THC metabolizes at an exponential rate, having them take the test hours after the time of arrest does not accurately reflect the THC level at the time of the incident. The tests that are currently used at the station include blood or urine diagnostics which take around a month to get results back. Police departments want to buy our product to simplify the procedure and speed up the process.
