In a controlled experiment, cannabis users were much more likely to recall words that were never shown and struggled with tasks like remembering to do something later. Researchers found that THC disrupted many different memory systems at once. Surprisingly, moderate doses caused memory problems similar to higher doses.

After analyzing more than 20 clinical trials involving over 2,100 adults, researchers found no strong proof that cannabis products outperform placebos in relieving neuropathic pain. Even when small improvements were reported, especially with THC-CBD combinations, they weren’t large enough to make a real difference in daily life. Mon, 19 Jan 2026 00:11:47 EST https://www.sciencedaily.com/releases/2026/01/260118233547.htm https://www.sciencedaily.com/releases/2025/12/251224015651.htm Cannabis products with higher THC levels may slightly reduce chronic pain, particularly nerve pain, according to a review of multiple clinical trials. The improvement was small and short-lived, while side effects were more common. Products with little or no THC, including CBD-only formulations, showed no clear benefit. Researchers say more long-term studies are needed.

In mice, it relieved neuropathic pain quickly and didn’t cause the usual movement or memory side effects. Surprisingly, the pain relief didn’t use typical cannabinoid receptors, instead calming abnormal nerve activity more directly. The findings hint at new avenues for treating chronic pain and neurological diseases.

Surprisingly, common prescriptions like antidepressants were seen as helpful for overall mental health but fell short for eating disorder relief. Thu, 24 Jul 2025 10:42:21 EDT https://www.sciencedaily.com/releases/2025/07/250724040940.htm https://www.sciencedaily.com/releases/2025/06/250607231604.htm Cannabis use among older Americans has climbed dramatically, with 7% of adults 65 and older now reporting recent use. This rise isn't just in numbers but also in diversity older users today are more likely to be women, college-educated, and higher-income. Researchers suggest legalization and growing social acceptance are contributing factors, especially in states with medical marijuana laws. The trend is especially notable among those with chronic illnesses, raising both opportunities and concerns for medical professionals trying to balance symptom relief with the complexities of aging.

Researchers say the condition occurs in people who are long-term regular consumers of cannabis and causes nausea, uncontrollable vomiting and excruciating pain in a cyclical pattern that often leads to repeated trips to the hospital. Thu, 20 Feb 2025 12:29:31 EST https://www.sciencedaily.com/releases/2025/02/250220122931.htm https://www.sciencedaily.com/releases/2025/01/250128123644.htm A new study explores the effects of both recent and lifetime cannabis use on brain function during cognitive tasks. The study, the largest of its kind ever to be completed, examined the effects of cannabis use on over 1,000 young adults aged 22 to 36 using brain imaging technology. The researchers found that 63% of heavy lifetime cannabis users exhibited reduced brain activity during a working memory task, while 68% of recent users also demonstrated a similar impact. This decline in brain activity was associated with worse performance on working memory -- the ability to retain and use information to perform tasks. For example, working memory allows a person to follow instructions they've just been given or to mentally visualize and manipulate information, like solving a math problem.
