Changes in regulation for cannabis for nonmedical use (CNMU) are underway worldwide. Switzerland amended the law in 2021 allowing pilot trials evaluating regulative models for cannabis production and distribut...

The increased legalization of cannabis over the past several years can potentially increase its co-use with alcohol. Concerningly, very few studies have looked at the effects of these two drugs when used in combination. In a series of new studies, researchers at used rats to understand how brain structure and behavior can change when cannabis and alcohol are taken together.

A 20-year study examined the long term relationship between cannabis and illicit opioid use. Overall results were inconsistent and showed no strong link. The study showed that clinicians and policymakers should be cautious about relying on cannabis to reduce opioid use, especially in the US and Canada.

In animals, the endocannabinoid system regulates multiple physiological functions. Like humans, animals respond to preparations containing phytocannabinoids for treating several conditions. In Argentina, laws ...

A new analysis of the genomes of more than 1 million people has shed light on the underlying biology of cannabis use disorder and its links to psychiatric disorders, abuse of other substances such as tobacco, and possibly even an elevated risk of developing lung cancer.

Medical cannabis (MC) is increasingly used for chronic pain, but it is unclear how it aids in pain management. Previous literature suggests that MC could holistically alter the pain experience instead of only ...

Global interest in hemp cultivation and utilization is on the rise, presenting both challenges and opportunities for African countries. This article focuses on Ghana’s potential to establish a thriving hemp se...

In a mouse study designed to explore the impact of marijuana's major psychoactive compound, THC, on teenage brains, researchers say they found changes to the structure of microglia, which are specialized brain immune cells, that may worsen a genetic predisposition to schizophrenia.

The is a case of a 28-year-old male presenting to an emergency department (ED) via emergency medical services (EMS) with a chief complaint of “gastritis.” He was noted to have bigeminy on the pre-arrival EMS e...

Researchers showed that consuming THC while pregnant could potentially affect development of the fetus and lead to life-long health impacts for offspring.

Researchers analyzed THC levels in the breath of people who use cannabis regularly, both before and after they smoked marijuana. The researchers found that THC levels spanned a similar range across pre- and post-use samples. 'In many cases, we would not have been able to tell whether the person smoked within the last hour based on the concentration of THC in their breath,' said study author.

Marijuana (cannabis) is well known for giving people the 'munchies.' Not only does it make people want to eat more, but it also makes them crave the tastiest, most high-calorie foods. Now a new study shows that well-studied nematode worms (C. elegans) react to those chemicals known as cannabinoids in precisely the same way.

Simultaneous cannabis and alcohol use, defined as using both substances at the same time so their effects overlap, increased in adults from 2008 to 2019, according to new research. Shifts in cannabis legislation have raised questions about unintended effects on cannabis and alcohol use patterns, whereby policy changes might lead people to use both substances. Until now, the relationships between recreational cannabis laws (RCLs) and changes in simultaneous cannabis/alcohol use prevalence had remain untested.

Pregnant women living in U.S. states where cannabis is legal must be screened for the drug, for the health of both mother and baby, claim scientists who in a new national study have found that they are far more likely to use the substance.

States that legalized recreational cannabis saw a slight population-level uptick in alcohol consumption that was largely driven by young adults and men, according to new research.

New research has found no evidence that cannabidiol (CBD) reduces the negative effects of cannabis.

Chemists have developed a fuel cell sensor that they hope to develop into a handheld analyzer to detect THC on a person's breath. When THC is introduced into their laboratory-scale device it oxidizes, creating an electric current whose strength indicates how much of the psychoactive compound is present.

In new study, opioid use seen to reduce or stop altogether, following prescription of medical cannabis.

A new first-of-its-kind study of twins finds that residents of states where recreational marijuana is legal use it 24% more frequently than those in states where it's illegal. It's among the strongest evidence yet that legalization increases use.

People who use therapeutic cannabis are more likely to also use nicotine products than the general population, according to a new study.

Plant biologists have defined the high-efficiency 'hacks' that cannabis cells use to make cannabinoids (THC/CBD). Although many biotechnology companies are currently trying to engineer THC/CBD outside the plant in yeast or cell cultures, it is largely unknown how the plant does it naturally.

Largest ever study into the health effects of different types of cannabis highlights concerns about stronger forms of the drug.

A new study found that rates of cannabis use and daily cannabis use have increased across the U.S., and current cannabis use and daily use are substantially higher among individuals residing in states that have legalized recreational cannabis use. Rates of cannabis use are even higher among Americans 12 and older who smoke cigarettes, and who reside in states with recreational cannabis laws, compared to those who live in states where cannabis was illegal in 2017.

Adolescents are over three times more vulnerable to developing a cannabis addiction than adults, but may not be at increased risk of other mental health problems related to the drug, according to a new study.

A new study found visits to the emergency department and hospitalizations are 22 per cent higher among individuals who use cannabis compared with those who do not. The findings also show serious physical injury and respiratory-reasons were the two leading causes of ED visits and hospitalizations among cannabis users.

Evidence behind the effectiveness of cannabis-related products to treat chronic pain is surprisingly thin, according to a new systematic evidence review. Voters in a number of states have legalized medical and recreational marijuana; however, the researchers found many of the products now available at U.S. dispensaries have not been well studied.

Cannabis vaping is increasing as the most popular method of cannabis delivery among all adolescents in the U.S., as is the frequency of cannabis vaping, according to researchers.

Students at four-year colleges and universities drink nearly twice as much alcohol as their peers in two-year colleges, according to a survey of college students in the Seattle area. On the other hand, students in community colleges and other two-year institutions use marijuana nearly twice as often as four-year students.

Some cannabis edibles look remarkably like popular snack foods and may be easily confused for them, finds a new study.

Cannabis use among pregnant women is on the rise and may be associated with negative health outcomes in children, according to a new study.
