Australian Researchers Find Lacking Evidence To Support Cannabis ‘Hangover’ Claims

When cannabis opponents speak out against cannabis they incorporate a variety of talking points, with some being more ridiculous than others. It seems as if some opponents will do or say just about anything to portray cannabis use in a negative fashion.
One argument that seems to be deployed at an increasing rate is that ‘cannabis causes hangovers.’ In an example of the sad hypocrisy that often accompanies anti-cannabis propaganda, very rarely, if ever, do those same cannabis opponents call for an end to alcohol sales due to hangovers.
Furthermore, while there is ample evidence that alcohol use can result in hangovers, researchers in Australia have found that the same is not true for cannabis, despite what cannabis opponents may claim. Below is more information about it via a news release from NORML:
New South Wales, Australia: The majority of available data fails to support claims that cannabis may potentially impact either cognitive function or subjects’ performance of safety sensitive tasks 24 hours after consumption, according to a review of the scientific literature published in the journal Cannabis and Cannabinoid Research.
A team of Australian researchers reviewed data from 20 studies involving 458 subjects. Selected studies assessed subjects’ performance 12 to 24 hours following THC dosing.
Investigators failed to identify any evidence of so-called THC-specific “next-day effects” in 16 of the 20 studies reviewed.
They concluded: “A small number of lower-quality studies have observed negative (i.e., impairing) ‘next day’ effects of THC on cognitive function and safety-sensitive tasks. However, higher-quality studies, and a large majority of performance tests, have not. Overall, it appears that there is limited scientific evidence to support the assertion that cannabis use impairs ‘next day’ performance.”
Authors further opined that the imposition of workplace drug testing policies that detect the long-term presence of cannabis metabolites and impose sanctions upon those who test positive for them are arguably not justified by the available data.
