Cannabis

College students with a higher risk for bipolar disorders report more life disruptions from cannabis use. Meanwhile, those who naturally experience higher levels of happiness tend to consume the drug less frequently.

As cannabis use grows among older adults, so do concerns about memory loss. However, a new study found that prior or occasional cannabis use is not associated with faster cognitive decline or a higher risk of dementia.

Despite its popularity, a new meta-analysis shows that CBD provides no meaningful benefit for patients with psychosis. Scientists note the treatment is well-tolerated but fails to outperform placebos in managing hallucinations, delusions, or cognitive issues.

A new study found that two minor cannabis compounds, CBN and THCV, were more effective at reducing voluntary alcohol drinking in rats than CBD, offering a potential new avenue for treating alcohol use disorder.

A new clinical trial mapped the sleeping brains of people with insomnia after they took a cannabis-based drug. The treatment altered deeper sleep stages and reduced dreaming, though participants experienced no cognitive impairment the morning after.

A study of over 500,000 Americans suggests that substances like PCP and cannabis consistently predict higher arrest rates. Conversely, psilocybin is associated with lower odds of offending, though these protective effects vary by race and age.

A massive new meta-analysis reveals a staggering overlap between cannabis addiction and depression. Researchers found that over 30% of people with Cannabis Use Disorder also suffer from Major Depressive Disorder, highlighting a critical need for dual-diagnosis mental health treatments.

Adolescents with a cannabis addiction are more likely to develop schizophrenia and depression than peers addicted to other substances. A recent study shows that this risk pattern reverses in adults, highlighting the vulnerability of the developing brain.

Does addiction always hijack your eyes? A surprising new Australian study found that heavy cannabis users don't actually pay more automatic attention to weed-related images than non-users, challenging long-held theories about how cannabis use disorder works.

A new review in Brain, Behavior, and Immunity challenges the idea that cannabis is strictly anti-inflammatory. Analyzing over 54,000 people, researchers found that regular cannabinoid use is linked to both pro- and anti-inflammatory immune responses.

By studying humans and rats, researchers pinpointed how cannabis causes hunger. The plant interacts directly with brain receptors to increase the reward value of food, driving consumption regardless of the body's caloric needs.

A new study in the Journal of Psychopharmacology mapped how cannabis impacts human cognition. The findings provide evidence that intoxication broadly disrupts multiple memory domains, increasing false memories and making it harder to recall practical, everyday information.

In a controlled laboratory setting, heavy drinkers consumed up to 27 percent less alcohol after smoking cannabis. The findings offer new insights into how acute cannabis intoxication alters immediate drinking habits and delays the onset of alcohol consumption.

Cannabis can trigger paranoia, but a new study finds that adults who experienced emotional abuse or a high-conflict childhood are uniquely vulnerable. Researchers discovered a toxic interaction where heavy THC consumption significantly amplifies the hyper-vigilance and mistrust caused by early...

A new brain imaging study reveals an association between overlapping depression and cannabis use and less efficient brain communication. The heightened connectivity typically seen with cannabis use is less pronounced when depression symptoms are present.
