Community Hospital of the Monterey Peninsula said in April the hospital had the most emergency room admissions, 42, for drug overdoses."We're seeing a lot of fentanyl, we're also seeing a lot of combinations with methamphetamines, and then some of these designer synthetics that are taking some time to get information back on," Dr. Reb Close, who is the founding physician of the "prescribe safe" initiative for Monterey County, said. "We're seeing, unfortunately, it's gone up and it's not going down."Close said drug dealers are lacing commonly used drugs with "ultra-potent" substances such as benzodiazepines, often referred to as "benzos", and Close says the drug acts similar to alcohol."The one I'm seeing the most in Monterey County right now is Etizolam. These drugs have no legal U.S. use," Close said. "They're basically brought in from other countries for the purpose of putting into the adulterated drug supply. You can not get them in the U.S. legally, as of this time. Some of my patients that are more savvy say, 'I don't really know what's in my body. I don't know what I'm taking.'"Close said that she's hearing from patients in the emergency room that the potency of the drugs can attract users. Close also said she has patients in the emergency room who tell her they use fentanyl every day."The problem is that if you're looking for the high, or you're needing something to have something incredibly potent to get out of the withdraw and you're hearing that someone just overdosed from a product that they got from this particular dealer, you actually would seek that out as a possibility," Close said.More than 40 pounds of fentanyl were seized and seven people were arrested at two homes in Oakland and San Leandro this past week in what authorities said was the largest federal seizure of the deadly drug in Northern California, the U.S. Attorney’s Office announced.The Drug Enforcement Agency said they've confiscated more fentanyl in Northern and Central California in the first five months of 2021 than in all of 2020.
