Australia has the world's scariest animals and most potent pot

Marijuana aficionados may be surprised to know that the state of New South Wales, Australia, is home to weed that packs a massive wallop. Make your Down Under vacation plans now, folks. The region may have the most potent mary jane on the planet. But there’s a flipside to the "good" news. Authorities are worried that the off-the-charts levels of psychoactive THC could cause mental health issues and dependency. In fact, the THC content is so powerful that Australian authorities might consider it a hard drug, based on a study by the National Drug and Alcohol Research Centre. The research was conducted on marijuana seized in regions such as Tweed Heads, Byron Bay and Lismore. Tweed Heads? No way.
