Surely the illegal cannabis industry used more electricity than the legal industry. It's much more efficient to have mass production than people growing in their closets. Colorado is likely just seeing a concentration of growers because they are a center of cultivation. They are simply picking up slack from the states that have yet to legalize.

Also, why are we blaming the cannabis industry for fossil fuels? We should be blaming the power companies who still use the fossil fuels, rather than blame their customers.

As a result, producing just a couple of pounds of weed can have the same environmental toll as driving across America seven times.

Okay so lets say that you smoke 1g per day, a moderate amount. Let's say 2 pounds of weed takes the same amount of energy as driving across America seven times. 2 pounds is a LOT of weed. Thats ~908 grams. This would take you 2.49 years to smoke if you smoked about one FAT blunt every day.

According to the DOT (https://www.fhwa.dot.gov/ohim/onh00/bar8.htm), the average American drives 16,550 miles per year. According to this website (http://www.worldatlas.com/webimage/countrys/namerica/usstates/uslandst.htm) the horizontal width of America is 2680 miles. This means that the average American drives "across the country" 6.18 times per year.

This means that driving a car an average amount uses 2.20 times more energy per year than smoking weed.

Seems to me that cars take the cake for being the glutton of fossil fuels, especially since power plants typically operate at much higher efficiency levels that individual car engines.

This is also an issue that will be fixed by renewable energy, whereas cars will not until people upgrade to electric motors.
