Swiss customs officers uncovered 3, 192 cases of drug smuggling in 2005, 240 fewer than in 2004, the Federal Customs Office said on Tuesday.
The volume of cocaine seizures dropped more than 100 kg to 167 kg in 2005, while the heroin haul sank from 97 kg to 57 kg, said the office in an annual report.
It added, however, that 2005 was a bumper year for cannabis smuggling, with customs stopping almost twice as much of the drug as in 2004 at 296 kg.
Greater quantities of ecstasy, LSD and amphetamines were also found.
