As predicted, recreational marijuana is here in California. California joined Nevada, Oregon, Washington, Colorado, Maine, Vermont, Massachusetts, and the District of Columbia in legalizing both medical and recreational marijuana. Thirty states and the District of Columbia have legalized medical marijuana. The trend of states in the expanding legalization of marijuana has had tech companies scrambling to become the first to develop a marijuana breathalyzer.
However, a California company has recently claimed to have cracked the code.
California Vehicle Code section 23152(e) makes it illegal to drive a vehicle while under the influence of drugs including marijuana. Unlike California’s DUI of alcohol law, there is no legal limit for marijuana, or more specifically, tetrahydrocannabinol (THC) the psychoactive component of marijuana. Therefore, a person can only be arrested and convicted of a marijuana DUI if the ingestion of marijuana impairs a person’s ability to drive a vehicle as a sober person would under similar circumstances.
To prove that a person is driving under the influence of marijuana, a prosecutor can use officer observations of driving patterns, observations during the traffic stop, performance on field sobriety tests, and the presence of THC in any blood test done.
Although THC can be detected in quantities of nanograms per milliliter of blood, the quantification is unlike alcohol in that the degree of impairment is unrelated to the amount of THC in a person’s blood. With alcohol, there is a fairly accurate correlation between a person’s blood alcohol content and how impaired they are. Therefore, unlike alcohol where prosecutors only need to prove that a person’s BAC was above a 0.08 percent, with marijuana, prosecutors can only prove that a person was “under the influence.”
Since “under the influence” is an extremely subjective standard, it is often very difficult to prosecute DUI of marijuana cases. This is especially true if the driver refused to perform the field sobriety tests and/or the officer did not observe driving that would be indicative of someone who is under the influence of marijuana.
Hound Labs, located in Oakland, California, is hoping to bridge the gap for officers and prosecutors.
“We are trying to make the establishment of impairment around marijuana rational and to balance fairness and safety,” said Hound Labs CEO Mike Lynn.
The company is claiming that it has developed a breathalyzer that can detect whether a subject has ingested marijuana in the last two hours, which many to consider the peak time for marijuana impairment after ingestion.
“When you find THC in breath, you can be pretty darn sure that somebody smoked pot in the last couple of hours,” Lynn says. “And we don’t want to have people driving during that time period or, frankly, at a work site in a construction zone.”
If accurate, Hound Labs would be the closest to developing this type of technology. However, thus far, no company has yet developed a machine to detect actual impairment.
According to Lynn, law enforcement are trying to determine who is impaired as opposed to “”somebody who smoked maybe yesterday or a few days ago and is not impaired. They’re not in the business of arresting people that are not impaired when it comes to marijuana. That makes no sense at all.”
Several law enforcement agencies will begin testing Hound Lab’s breathalyzer this fall. “They’re interested in it providing objective data for them at the roadside,” says Lynn. “That’s really the key, objective data at the roadside — just like we have for alcohol.”
For those of you who think that it is safe to smoke some marijuana and get behind the wheel, be aware that law enforcement could be out with a new roadside tool at their disposal to confirm that you have smoked within two hours, that is if Hound Labs’s new device does that it claims it can do.
