Australia has seized more than AUS$1 billion (US$760 million) of methamphetamine in its biggest ever bust of the highly-addictive drug, police said on Friday. The massive 1.2 ton haul was intercepted after being offloaded from a boat, the Valkoista, which authorities believe came from China. Eight men, all Australian, were charged with either importing a commercial quantity of a border controlled drug, or possessing a commercial quantity of a border controlled drug, AFP reports. Australia has the world’s highest per capita consumption of crystal meth. Much of the ice comes from China and the Golden Triangle region where the borders of Myanmar, Thailand and Laos meet.
