Insufficient evidence that medicinal cannabinoids improve mental health

Mon, 2019-10-28 19:39
The most comprehensive analysis of medicinal cannabinoids and their impact on six mental health disorders -- combining 83 studies including 3,000 people -- suggests that the use of cannabinoids for mental health conditions cannot be justified based on the current evidence. This is due to a lack of evidence for their effectiveness, and because of the known risks of cannabinoids.

Evidence of behavioral, biological similarities between compulsive overeating and addiction

Thu, 2019-10-17 10:52
Does yo-yo dieting drive compulsive eating? There may be a connection. According to researchers the chronic cyclic pattern of overeating followed by undereating, reduces the brain's ability to feel reward and may drive compulsive eating. This finding suggests that future research into treatment of compulsive eating behavior should focus on rebalancing the mesolimbic dopamine system -- the part of the brain responsible for feeling reward or pleasure.

A rat's brain, on and off methamphetamine

Wed, 2019-10-16 10:45
Drug addiction is a vicious cycle of reward and withdrawal. Chronic users often relapse because of the unpleasant physical and psychological symptoms they experience when they stop taking the drug. Now, researchers report metabolic changes in the brains of rats during methamphetamine self-administration and withdrawal that could help identify biomarkers and treatments for addiction.

Potential therapy to treat detrimental effects of marijuana

Tue, 2019-10-15 07:22
A new study using a preclinical animal model suggests that prenatal exposure to THC, the psychoactive component of cannabis, makes the brain's dopamine neurons (an integral component of the reward system) hyperactive and increases sensitivity to the behavioral effects of THC during pre-adolescence.

Older adults with COPD more likely to use synthetic cannabinoids

Mon, 2019-09-23 11:09
Chronic obstructive pulmonary disease (COPD) is a progressive lung disease that's often associated with a variety of health problems, including chronic muscle pain and insomnia. Psychoactive drug classes, like cannabinoids, are often prescribed to help reduce pain, promote sleep and decrease breathlessness. A study has found that older adults with COPD were twice as likely to use prescription synthetic oral cannabinoids compared to older adults without COPD, raising safety concerns.

A safer way for police to test drug evidence

Tue, 2019-09-17 09:54
Scientists have demonstrated a way for police to quickly and safely test whether a baggie or other package contains illegal drugs without having to handle any suspicious contents directly. The new technique can limit the risk of accidental exposure to fentanyl and other highly potent drugs that can be dangerous if a small amount is accidentally inhaled.

Medical marijuana laws impact use among sexual minorities differently than heterosexuals

Wed, 2019-09-04 09:32
Bisexual women had higher rates of past-year and daily marijuana use compared to heterosexual women, and gay/lesbian women were also more likely to report daily marijuana use and past year medical marijuana use than heterosexual women. While previous research has explored the association between state-level medical marijuana laws and marijuana use and MU disorder among the general US population, this is among the first to explore this relationship for lesbian, gay and bisexual individuals.

Gene linked to autism undergoes changes in men's sperm after pot use

Tue, 2019-08-27 10:35
A specific gene associated with autism appears to undergo changes in the sperm of men who use marijuana, according to new research. The gene change occurs through a process called DNA methylation, and it could potentially be passed along to offspring.

New breathalyzer can detect marijuana

Tue, 2019-08-27 10:32
A team has developed a breathalyzer device that can measure the amount of tetrahydrocannabinol (THC), the psychoactive compound in marijuana, in the user's breath. The breathalyzer was developed using carbon nanotubes, tiny tubes of carbon 100,000 times smaller than a human hair. Nanotechnology sensors can detect THC at levels comparable to or better than mass spectrometry, which is considered the gold standard for THC detection.
