Mexico President Claudia Sheinbaum addresses fentanyl production following Trump's tariff threat

Mexico isn't the sole source of fentanyl, its president said Tuesday at a news conference for the country's anti-drug campaign, just weeks after threats from President-elect Donald Trump to impose tariffs over drug trafficking. 

"So far, we have not found that precursors arrive, because most of the precursors come from Asia, and that the whole process is manufactured here in Mexico," President Claudia Sheinbaum said. "The laboratories that have been dismantled in our country are mainly for methamphetamine or crystal (meth)." 

Sheinbaum stressed that her government was committed to combating illegal drug distribution. In recent weeks, Mexican authorities have announced several major seizures of fentanyl — a synthetic opioid 50 times more potent than heroin — as well as chemical precursors. Officials said last month that the seizure of over a ton of fentanyl pills was the biggest in the country's history.
