Does anyone else find this ridiculous? Now Marijuana causes global warming, one can only imagine the amount of fuel and energy wasted in the tobacco and alcohol industries but shit, Marijuana must be to blame for global warming and not those innocent companies....

People growing marijuana indoors use 1 percent of the U.S. electricity supply, and they create 17 million metric tons of carbon dioxide every year (not counting the smoke exhaled), according to a report by Evan Mills, an energy analyst at the Lawrence Berkeley National Laboratory in California.

In order to produce some 17,000 metric tons of marijuana this year, Mills estimates authorized growers will use $5 billion worth of energy. That works out to the output of seven big electric power plants.
