But we talked to the man behind the international-headline-making research today, and he doesn't want to turn this into a prosecution of the hippie cannabis club.
No, in fact, says Lawrence Berkeley National Laboratory researcher Evan Mills, his work points, perhaps, to the need for further decriminalization efforts. Say what?
Yeah, maybe he's right. Here's his rationale:
If cultivating hydroponic weed is bad for the environment (and it is -- indoor production is the equivalent of half of America's household computer use, Mills says), then maybe we should encourage eco-friendly grow methods.
But, Mills points out, that would be hard to do since one of the primary reasons for indoor growing is that it is out of site of law enforcement. "Criminalization certainly contributes to the problem in forcing it indoors," he says.
In fact, cultivating large amounts of cannabis is a legal gray area in California, where you're really only allowed to grow enough for the other seriously ill people in your collective.
Some cities such as Berkeley have recognized the folly of trying to follow the letter of the law and now allow grow operations that are "carbon neutral," thus encouraging them to find more fuel- and electricity-efficient grow appliances (lights, fans, heaters).
One of the great inefficiencies of the grow house, Mills says, is that some operators have turned to using diesel and gas portable generators so they'll stay off the grid and away from the cross-hairs of the law.
(A tried-and-true method of tracking grow houses is simply to check for unusually high electricity bills compared to those of neighbors').
