Weeding out marijuana

In a first step toward engineering a drug-free Cannabis plant for hemp fiber and oil, University of Minnesota researchers have identified genes producing tetrahydrocannabinol (THC), the psychoactive substance in marijuana. Studying the genes could also lead to new and better drugs for pain, nausea and other conditions. The lead author is David Marks, a professor of plant biology in the College of Biological Sciences.

The study revealed that the genes are active in tiny hairs covering the flowers of Cannabis plants. In marijuana, the hairs accumulate high amounts of THC, whereas in hemp the hairs have little. Hemp and marijuana are difficult to distinguish apart from differences in THC.

or weed can just be legal

[meggatonman]

They should be finding out ways to genetically pump MORE thc into those badboy plants. It would make the world a better place for all

[grunder20]

marijuana must be legalized!

[grunder20]

marijuana is herbal. it has many benefits to the body. it can cure cancer, depression, frustration, and so many scientists have proven this conclusion.

[thegreeensky]

drug free marijuana? that would be a breakthrough....

[iiTzOLLZ]

you're doing it wrong..

[DamianiWins]

FUCK YOU GEORGE WEIBLEN YOU'RE TRING TO PLAY GOD KNOCK IT OFF. SAY NO TO GMO CANNABIS!!!!!!!!

[babyfran05]

wtf is the point of that?

[marijuananewschannel]

Well, marijuana is Americas #1 Cash Crop, too bad its illegal. Hemp restores soil fertility so that aspect is very inviting I would hope that MN could be a leader in this new technology and manufacturing of raw hemp materials and thanks for pointing out that the hemp products we buy comes from imported hemp-stock.

OH NO HEMP HAS LIKE .5 to 1% THC. WHAT ABOUT THE CHILDREN? Seriously, you are never going to get a significant amount of THC in hemp, also, GUESS WHAT? Hemp looks different from marijuana....

[ungougedeyes552]

@Schlauton yes, there was industrial hemp plants here before it was prohibited and criminalized. they're too stupid to grow them again cuz they don't know how to grow plants with minimal thc

[MrSleeps]

yes boys and girls our dumb ass government buys industrial hemp from other countries because, the dumb ass government says that it has no medical value and is addictive. this plant is talked about there is no logical use for it by our government but yet we buy it from other countries. can you say hypocrites.
