Average THC Percentage of Cannabis in France has Risen Nearly 200% Since 2009 and 650% Since 1995

thc percentageThe average THC percentage in France’s cannabis has risen rapidly in the past several years, according to new research.

The study was published in the journal Forensic Science International, and published online by the U.S. National Institute of Health.

The study’s abstract starts with some basic information for those unfamiliar with cannabis:

Cannabis contains a unique class of compounds known as the cannabinoids. Pharmacologically, the principal psychoactive constituent is Δ9-tetrahydrocannabinol (THC). The amount of THC in conjunction with selected additional cannabinoid compounds (cannabidiol/CBD and also cannabinol/CBN), determines the strength or potency of the cannabis product. Recently, reports have speculated over the change in the quality of cannabis products, from nearly a decade, specifically concerning the increase in cannabinoid content.

For the study, researchers examined the “analytical data of cannabis samples analyzed in the five French forensic police laboratories over 25 years.”

The increase potency of both herbal and resin cannabis in France “is proved through the monitoring of THC content.”

Cannabis resin now averages 23% THC; however, it averaged just 10% in 2009.

Herbal cannabis now has a THC percentage of 13; it averaged 7% in 2009 and just 2% in 1995.

Therefore, researchers state that; “The calculation of THC/CBD ratios in both herbal and resin samples confirms the recent change in chemotypes in favor of high potency categories.”

    We had Thai, Colombian, Panama, Indian hash, Jamaican and more back in the 70’s. The high thc stuff was out there, but wasn’t always available and Mexican weed wasn’t always as shitty as most think. Anyway, the price was right at $115/lb for Mexican and $50/oz for the good shit.

    The good news in this, in France or anywhere, is that 500-mg Hot Burning Overdose Monoxide Puffpaper Joints are obsolete, you can get the appropriate amount of THC from one or two 25-mg single tokes of #16 screensifted flowerbud using a quarter-inch-diameter flexdrawtube onehitter (illustration and DIY directions in the free wiki article “Make Pipes from Everyday Objects”)! After each toke, breathe 30 warm wet W’s in and out of a breathbonnet (breadbag).
    .
    The main threat from cannabis use in France, and elsewhere, has been and remains the practice (taught to youngsters starting out by those who seem to know what they’re doing) of mixing cannabis (often hashish, on the grounds that it’s necessary to make it burn) into a joint with addictive nicotine $igarette tobacco. The Australian Department of Health published a document referring to this practice as a “Trojan Horse” luring young persons, who were seeking to experiment with cannabis, into lifelong deadly $igarette $moking. Health and character damage then conveniently blamed on the cannabis– but you knew that already, right?

    The good stuff has always been 23%. This “average” thing only shows there is less shwag on the market, nothing else.
