New Study Finds No Link Between Cannabis Use and Cognitive Decline in Men
A recent study of over 5,000 men in Denmark has found that long-term cannabis use does not contribute to cognitive decline in older age. The study, which tracked participants from age 18 to 64, found that men who used cannabis regularly showed no significant decline in cognitive function compared to non-users.
The researchers used Denmark’s conscription board intelligence test to measure cognitive decline, and found that cannabis users showed a 1.3-point less decline in IQ scores compared to non-users. This difference, while statistically significant, may not have clinical significance, according to the study’s authors.
The study’s findings are in contrast to those of tobacco and excessive alcohol use, which have been linked to faster cognitive decline. However, the researchers note that more research is needed, particularly among heavy and continuous cannabis users.
The study’s authors also found that the age at which cannabis use began and the frequency of use did not have a significant impact on cognitive decline. Additionally, the study found that the negative effects of cannabis on cognitive function may be reversible with prolonged abstinence.
The study’s findings are in line with previous research from Australia, which found no link between cognitive decline and cannabis use in middle-aged men and women. However, other studies have found a link between cannabis use and cognitive decline, particularly among current users.
The study’s authors note that cannabis use has become increasingly popular, but there is still a lack of research on its long-term health effects. This study provides new insights into the potential effects of cannabis use on cognitive function, and highlights the need for further research to fully understand the plant’s effects on the brain.
The study was published in the journal Brain and Behavior.
