Venezuela to Macedonia - WTF?

The BBC reports that Macedonian police confiscated 400 kg of Venezuelan cocaine from a truck headed to Greece. It was the largest drug bust in Macedonian history, and the contraband was estimated to have a $50 million street value.

I wonder....

• is Venezuela a player in the War on Drugs? I wonder how much Hugo Chavez knows.
• how on Earth does 400 kg of anything - especially illegal cargo - get from Venezuela to Macedonia?
