At Halent, we recently tested a strain called ‘Cannatonic’ to contain 22% CBDA and only 0.7% THCA! That's a ratio of 30 to one.
Sacramento, CA (PRWEB) February 25, 2012
Halent Laboratories, a Bay Area cannabis testing lab, has only been testing medicinal cannabis samples for about a year, but has already found some startling new results. The lab has identified several strains containing unexpectedly high amounts of cannabidiol (CBD) and tetrahydrocannabivarin (THCV). Studies have shown these two compounds have great medical benefit. For example, CBD gives significant pain relief without causing the euphoric feeling associated with the most well-known cannabis compound, THC.
THC also relieves pain, stimulates appetite, can relieve symptoms of post-traumatic stress disorder (PTSD), and has many other important medicinal effects. Halent, like all other cannabis testing laboratories, reports the THC content for all samples.
But other compounds are also of great medical interest. CBD is also an excellent pain reliever—in some ways, superior to THC—and it can relieve pain while imparting little or no psychoactivity. Thus, strains that produce high levels of CBD and low levels of THC afford most patients the ability to treat pain with cannabis with no impairment of their normal physical or mental activities. Plants actually produce the “acid” forms of cannabinoids, labeled with an “A” at the end, like THCA, which, when heated, produces THC.
“At Halent, we recently tested a strain called ‘Cannatonic’ to contain 22% CBDA and only 0.7% THCA! That's a ratio of 30 to one,” says Donald P. Land, Ph.D., President/Chief Scientist at Halent. “Cannatonic is a strain that is known to sometimes produce high levels of CBD, but this is the highest (and highest ratio) of which we are aware.”
Another recent test on a sample called "Wizard" showed a content of almost 13% CBDA with THCA at less than 5%. To Halent’s knowledge, this is the first observation of a sample of Wizard showing high CBD production, and the ratio is among the highest observed.
One very surprising result is that a sample labeled as (and physically resembling) "Train Wreck" also had a significant amount of CBDA—measured at a whopping 16% CBDA with only 4% THCA—a four-to-one ratio.
“While Train Wreck is a rather common and popular strain, no sample of Train Wreck, to our knowledge, has ever been identified as a high CBD strain,” notes Land.
This highlights an important fact for patients to know: samples from the same strain don't always have the same content. In fact, some of the strains best known for their consistently high CBD content, such as Harlequin, sometimes don't have any appreciable amount of CBD.
“At Halent, we have measured samples of Harlequin, Cannatonic, and many other ‘high-CBD’ strains that have very little CBD and, instead, contain predominantly THC. The only way to really know for sure is if it is tested,” explains Land.
Another important compound rarely found at high levels in cannabis is THCV, which has been reported to be anti-epileptic (eases seizures) and anorectic (reduces the aversion towards eating and increases appetite). It has also been reported to stimulate bone growth.
In recently published results (British Journal of Pharmacology, August, 2011), testing in animals has shown THCV to be effective not only at reducing symptoms of Parkinson's disease, but also for slowing the progression of the disease. If this is true also for humans (and it is believed that it will be), this could be an incredibly important and unique medicine for Parkinson's sufferers.
“At Halent, in recent weeks, we have measured several samples that had significant amounts of THCV. One sample of Blackberry had almost 1% of THCVA with only ~9% of THCA. That ratio of 1 to 9 is significant, but we've seen even better. Another recent sample, Bakhye Shamonie, had almost 3% THCVA and a ratio of one to 3 relative to THCA. But the all-time winner, so far, has been Pineapple Purps, which tested at 5% THCVA and a ratio of 1 to 2 relative to THCA,” Land says.

About Halent Laboratories
Halent Laboratories is a Bay Area medical cannabis testing lab dedicated to the idea that medicinal cannabis is more than just THC, and, with proper testing, patients can be empowered to get the medicine that will help them most.
Halent mandates that all samples submitted be screened for safety by testing for molds, mycotoxins, pesticides and other dangerous contaminants. In addition to safety screening, Halent has developed methods to test for over 20 compounds in cannabis that have been shown, through peer reviewed published research, to have beneficial medicinal effects. This includes 15 cannabinoids (compounds unique to cannabis) and eight terpenes (compounds produced by many different plants).
