A hangover is usually associated with alcohol and other drugs consumption, while marijuana users are believed to be free of these aftereffects. However, some of them report experiencing hangover symptoms after consuming THC. So, can marijuana cause a hangover? And what can science tell us on this matter?
Though many studies were conducted on this issue, most of them resulted in quite controversial findings. Researchers have divided into two groups regarding the hangover from weed: some of them claim that cannabis hangovers are real, while other do not agree with it.
The earliest study on this subject was carried out in 1985. After analyzing the morning condition of 13 participants, Chait et al. came to the conclusion that cannabis smoking could cause hangover effects on the next morning, but their further determination was required.
Another study was published by the National Institute on Drug Abuse in 1990. Heishman et al. also found that marijuana use could lead to residual effects that last up to 24 hours after smoking.
A 1995 study by Pope et al. not only showed the possibility of hangover in weed users but also determined its common symptoms, which included temporal reduction of attention, short-term memory loss, and psychomotor dysfunction.
Wadsworth et al. investigated how cannabis hangovers influence pot users at work. The researchers tested the participants' cognitive performance, errors, and mood, and discovered that marijuana could cause a hangover effect that may increase with every time the person consumes weed.
In contrast, there are some studies, the authors of which disproved the previous findings or received opposite results.
For instance, Chait, L.D. conducted a study on the matter and found no evidence of a cannabis hangover that is similar to that reported after the use of alcohol or other substances.
In addition, Fant et al. came to the similar conclusion after carrying out their 1998 research. The report published in the journal Pharmacology Biochemistry & Behavior states that smoking one cigarette of cannabis does not lead to any residual effects.
The researchers have not reached the same conclusion yet, and it should be noted that even the conducted studies are not reliable enough. All of them were limited by self-reported data of a small number of participants, and most of the studies used mild doses of marijuana.
However, some symptoms of a weed hangover can be determined based on the mentioned studies and anecdotal evidence from the reports on the web.
The list of possible physical symptoms includes the following:
The possible cognitive symptoms may be the following:
All the mentioned symptoms are less prominent than in the case of alcohol hangover and are usually experienced by a small percentage of marijuana users. But what are the reasons of cannabis hangovers?
