A study has found that cannabis intoxication, specifically THC, can affect memory, potentially creating false memories or distorting reality. The study suggests that cannabis use can disrupt various types of memory, although its impact on eyewitness recall is less clear, with some findings indicating that certain interview methods may mitigate memory impairment. The research appears to show that cannabis use can alter memory recall, but the extent and nature of this effect may vary depending on the context.
