Denver, Colorado - An estimated half a million happy puffers at Denver's first entirely legit 4/20 marijuana festival were accused of wanton destruction of the earth's ozone layer today.
World Fracking Council inspectors on a comparison exercise measured huge levels of cannabis emissions over Colorado before nearly passing out zombified from passive inhalation of the local Easter Bunny Bong weed according to their website.
Their upcoming report is tipped to reveal that the local atmosphere was 'pretty much totally stoned' in the beautiful Easter Sunday sunshine - a fantastic day to conduct such groundbreaking research.
The findings are likely to support Colorado's fledgling fracking industry's claims that hydraulic fracturing of cannabis deposits is an entirely safe procedure and worth every cent to the State in valuable tax dollars.
Tonight a low-lying cannabis fug is making its way slowly southwards where dope smoking restrictions still apply.
An ounce of Denver Dementia weeds sells for around $100 a quarter.
