Marijuana Potency on the Rise
The marijuana we smoke today is significantly stronger than the marijuana your parents were smoking in their younger years. In fact, today’s Marijuana is triple the strength on average than it was only 20 years ago.
The results come from a study two decades in the making, published in the journal biological psychiatry by the University of Mississippi. The study utilized over 40,000 different samples of marijuana and about 1,000 samples of Hash. The study showed an 8% increase in the amount of Δ 9 THC the psychoactive component in Marijuana, moving from 4% in 1995 to 12% in 2015. Of samples tested, 41% of marijuana tested greater than 12%.
While the Psychoactive benefits have increased over time, CBD, the cannabinoid most responsible for marijuana’s health benefits has decreased from 0.5% to 0.2%.
The trend in increasing THC is apparently worldwide. In France, the French monitoring center for Drugs and Drug Addiction found the average amount of THC in Cannabis to be 13% in 2013 – a massive boost from just 10% in 2012
The increase in THC percentage is likely not only the result of improved technologies but also increasing tolerances. It would seem higher tolerances demand a higher quality product and as individuals adjust to higher THC contents their response to lower quality marijuana is diminished.
We hope the trend continues everywhere. We want, no… demand, a universal 30% THC!
Stay Excellent. Party On.
High After-thought: An earlier draft of this study was published in 2010 in the Journal of Forensic sciences under the title Potency Trends of D9 -THC and Other Cannabinoids in Confiscated Cannabis Preparations from 1993 to 2008* but only produced results up to 2008.
