Cannabis Study Finds THC Can Create False Memories

Topic: Health

A new study from Washington State University found that people who consumed THC were more likely to recall words that were never shown to them and had trouble remembering everyday tasks. The research shows that cannabis affects not only simple recall but also several forms of memory.

Cannabis is known to affect memories, making it harder to remember things. But a new study from Washington State University has found that THC can actually create false memories. Researchers recruited 120 regular cannabis users and had them complete memory tests after consuming either a placebo or THC. The results showed that people who used cannabis were more likely to recall words that were never shown to them and had trouble remembering everyday tasks like taking medication or stopping at the store on the way home.

The study also found that cannabis can make it harder for people to remember where they learned something, which can be a problem in situations where accurate recall is important. For example, errors in memory or suggestive questioning during eyewitness interviews can influence how events are remembered.

This study is one of the most detailed examinations to date of how cannabis affects memory. It shows that even moderate amounts of THC can significantly interfere with memory.
