By 1996, federal prosecutors in the USA won at least 18 convictions of major smugglers, accompanied by millions of dollars in penalties and sentences of up to 57 months for the biggest violators. A freon case brought the first extradition for an environmental crime and the first United States felony convictions based on violations of the Federal Clean Air Act amendments on ozone-depleting gases.
In 1996, freon contraband was running second only to marijuana in the seizures made on the border between the USA and Mexico. It was more profitable than cocaine and believed to be bigger business than gun-running.
