Not all weed is created equal. Some members of the Cannabis genus pump out tetrahydrocannabinol (aka THC, the plant's main psychoactive chemical) like nobody's business, while others produce very little of the mind-altering molecule. But the genetic basis for why some plants excel at getting you high while others are best suited for, say, their use in textiles has long been a mystery. Until now.
2011 has been a good year for pot research. Back in August, a company by the name of Medicinal Genomics released the first complete sequence of the Cannabis sativa genome to the public, making it the first medicinal plant ever sequenced. But they only released the raw sequence, meaning the genetic data had yet to be assembled into meaningful chunks of genetic code.
