A new study found that Colorado's booming pot industry is causing more CO2 emissions than its coal - almost 50 percent more.

The reason is that marijuana in Colorado has to be grown in giant greenhouses which require air conditioning or heat, plus giant lights. This does not include emissions associated with storage and processing.

Like many progressive states, Colorado hates coal these days, but don't look for them to clamp down on pot to curb their CO2. It's too large of an industry. What is worrisome is that this study can't account for the illegal marijuana trade, and if you don't think that is booming you must be smoking paprika. With no accountability or oversight, they are overusing pesticides, it is laced with fungi and heavy metals, and they are powered by on-site diesel generators, which emits far more pollution than electricity from the grid powered by...coal.
