For the fourth consecutive year, researchers worldwide published over 4,000 scientific papers specific to cannabis, its active constituents and their effects. “Scientists’ interest in studying cannabis has increased exponentially in the past decade, as has our understanding of the plant, its active constituents, their mechanisms of action and their effects on both the user and upon society”, United States NORML’s Deputy Director Paul Armentano said. “It is time for politicians and others to stop assessing cannabis through the lens of ‘what we don’t know’ and instead start engaging in evidence-based discussions... that are indicative of all that we do know”.
Over the past decade, there has been a dramatic increase in scientific inquiries about the cannabis plant—with researchers publishing more than 35,000 scientific papers about cannabis since the beginning of 2014. Much of this uptick is a result of researchers’ newfound focus on cannabis’ therapeutic activities as well investigations into the real-world effects of legalisation laws. In all, more than 70% of all peer-reviewed scientific papers about cannabis have been published in the past ten years and over 90% of this literature has been published since 2002. As of December 2024, PubMed.gov cites over 49,500 scientific papers on cannabis dating back to the year 1840. Available to the public online since 1996, PubMed is a free resource supporting the search and retrieval of biomedical and life sciences literature.
