SAN DIEGO (KGTV) -- On January 1, it will be legal for businesses to sell pot in California. With that, the questions and concerns about what that means for drivers out on the roads.“I think we will see an increase in DUI marijuana’s,” said Officer John Perdue, a San Diego Police officer in the traffic division.Perdue is an expert at DUI and drug recognition. Since November 8, 2016, when California voters approved Prop. 64, or the adult use of marijuana act, he’s been hearing the same thing when he comes across drivers he suspects are driving high.“Their first reaction is one of two, either A. ‘I have a medical marijuana card’, or B. ‘marijuana is legal.’ And I have to remind them, so is alcohol, but you still can’t drive under the influence of it,” Perdue said.How exactly will police be able to tell if someone is driving high?One tool that officers will use to help is the Drager Drugtest 5000, a presumptive drug screening test that can detect seven types of drugs in a person’s system.Like an alcohol breathalyzer, Perdue said, “the person has every right to refuse this.” But unlike alcohol, it doesn’t have a percent limit.If the Drager reads positive, Perdue said, “it doesn’t necessarily mean they’re impaired or under the influence, it just says that chemical or drug is in their body.”  So to be arrested for DUI, it’s still up to the officer to decide if the driver shows impairment.But that can be tough. Look at the Drager as an extra tool that’s used along with field sobriety tests, what an officer smells, sees or finds in the car, to formulate that officer’s opinion of whether a driver is high.“The hardest thing will be, because there is no per se limit right now, the officers are really going to have to be aware of the signs and symptoms,” Perdue said. 1808

SAN DIEGO (KGTV) - Neighbors in College Area are a little more vigilant after a coyote attacking a chicken was caught on camera. Matt Dixon was grilling in his backyard when he heard squawking on the neighboring hillside. “One of the chicken flies into the fence,” said Dixon describing the video he took. “That’s when the coyote popped out of the clearing it there and made its way up and he eventually found what he was after.” Dixon posted the 28-second video online and found that people were quicker to forgive the coyote. “I got a lot of flak for not trying to help save the neighbor’s chicken and I can understand that,” said Dixon, “but it all happened so fast.” Other neighbors say they are more cautious with their children and pets outside knowing there can be coyotes in an urban area. 805

SAN DIEGO (KGTV) — Nearly three-quarters of the students in San Diego County are currently learning from home, and those numbers don’t make a lot of sense to MIT professor Martin Bazant.Bazant is one of the creators of the COVID-19 Indoor Safety Guideline. The free online tool simulates the fluid dynamics of respiratory droplets in various kinds of rooms to show users the risk of different indoor environments.“If you run the numbers for a typical classroom, especially if the students and the teachers are wearing masks, then the amount of time in the room can be very significant,” Bazant said. “Essentially those people could spend a week in the classroom and not have a problem.”Bazant says the six-foot rule that has largely determined which businesses can stay open is overly simplistic. In some cases, he says the rule creates a false sense of security. In other situations, he says it causes the closure of businesses or schools that could safely operate.“If you place nursing home beds six feet apart in a shared room, they are absolutely not safe,” he said. But he said well-ventilated classrooms, with teachers and students in masks, are another story.“It's only the United States where we follow the six-foot rule. That's given by the CDC. The World Health Organization all along has been saying one meter, which is about three feet. If you simply followed the one-meter rule, all our schools would be open, as they are in most of the world right now,” he said.Bazant and his colleague John Bush said they set out to design a tool that would reveal the risk of transmission based on science, not guesswork.Users start by selecting a room type, like a classroom or an airplane. From there, they can control a wide array of variables to dial in the risk, like the room size, the ceiling height, and the ventilation and filtration systems.From there, users can further tune the model by human behavior. How many people are in the room? Are they whispering, shouting or singing? How many are wearing masks?Mask usage is a critical component, Bazant says. The model quickly reveals the challenges of maskless activities in rooms with poor ventilation. Put five people without masks in a 400 square foot room with closed windows, and it becomes unsafe after 33 minutes.Bazant says studies on super spreader events show in indoor environments, the distance from an infected person doesn’t matter. Infected droplets spread and mix throughout the room like second-hand smoke from a cigarette.But with masks trapping droplets and diverting them upwards like a chimney, an environment like an airplane could be safe for several hours, according to the model. With more than 95% of the passengers and crew wearing surgical masks, a Boeing 737 could support 200 people -- around full capacity depending on the configuration -- for 18 hours. 2850
