UAB doctor talks impact, prevalency of carfentanil
Experts say carfentanil is chemically-related to fentanyl, although it's about 20 times more potent.
"If you ingest it, it's going to be a greater likelihood of causing an overdose," according to Dr. Stefan Kertesz with UAB's Division of Preventive Medicine.
Kertesz says there have been no recent overdose deaths in Jefferson County involving carfentanil. He also says there is no medical use for carfentanil in humans either.
"Carfentanil has been used by veterinarians to tranquilize large animals and sometimes it has been something that's put into the drug supply by drug dealers and distributors who want to make product more potent." Dr. Kertesz explains.
Kertesz is aware of a report of the lethal drug being found in a drug supply in Walker County, but he says official confirmation is still needed. He says fentanyl remains a primary concern for now.
"Right now, fentanyl seems to be everywhere and I would not expect carfentanil to replace it," Kertesz adds.
Experts say fentanyl is already such a potent drug that it would be hard for people to switch to something 20 times more potent like carfentanil.
"In our current market, occasionally, different kinds of junk drugs appear in the supply because dealers and distributors can do anything they want when the market is completely unregulated," Dr. Kertesz points out.
At the same time, he says dealers and distributors don't have a lot of incentive to use something as lethal as carfentanil.
