Minecraft has proven a useful tool for teaching life lessons. Also, cave exploration can be extremely dangerous without enough light, or if you run into molten lava — which is frequently. Now the US Food and Drug Administration is keen on tapping some of that environmental learning on people who might become addicted to cigarettes and tobacco. Ad Week reports that the public health agency has hired prominent Machinima video creator SkyDoesMinecraft to produce an anti-smoking PSA using Mojangs hit game. SkyDoesMinecraft, who is actually 21-year-old Adam Dahlberg, has 10.3 million subscribers, and his videos have been viewed more than 2.1 billion times.
