Skyrocketing potencies

There's a new marijuana trend and it poses new dangers for kids, reports Fox31. Nationally, the potency of marijuana has increased dramatically from an average of about 3.7% THC in the early 1990s. Average potency of flowers/buds in Colorado is now 17.1% THC while the average potency for concentrates is 62.1%. Potency rates of up to 95% have been recorded. 

"These super high concentrations of THC, we don't know what happens because we have not been studying it,” Dr. Kari Franson, associate dean at the University of Colorado School of Pharmacy, told Rocky Mountain PBS in a segment aired on 9News. While edibles in Colorado are now limited to 10 milligrams THC per serving, Franson said "dabbers" are "getting 80, 90 percent THC in a concentrated oil. And when they smoke it, they're taking in 600-to-800 milligrams of THC."

Here’s what Gov. John Hickenlooper told a reporter for “When you’re a teenager, your brain is growing very, very rapidly. The high-THC marijuana we have is so intense in the way it affects your synapses and those parts of your brain that literally every brain scientist I’ve talked to feels there’s a very high probability that, even if you only smoke once a week, this high-THC marijuana, if you’re a teenager, it will take a sliver of your long-term memory forever. That doesn’t come back in two weeks or three weeks. Your brain is growing so fast that the synapses don’t connect so you can’t retrieve information that you remembered.”

In short: “Modern weed is not your Woodstock weed.” Pueblo County Sheriff Kirk Taylor told the Pueblo Chieftain.

Here’s why potency matters:

  • Colorado has no limits on overall marijuana potency.
  • Research has not addressed the health impacts of ultra-potent pot.
  • We know marijuana is bad for teens so the effects of ultra-potent pot on developing adolescent brains is of particular concern.
