Cognitive Impairment Caused by Cannabis Use
Cannabis use can cause short-term cognitive impairments, impacting memory, attention, and executive function. Long-term or heavy use can lead to more severe and chronic cognitive issues.
How Cannabis Affects the Brain
THC, the primary psychoactive compound in cannabis, affects the hippocampus, a region critical for memory formation and learning. This can lead to memory impairment.
Long-Term Effects of Cannabis on Memory
Short-term Impairments
- Immediate effects include short-term memory loss, impaired attention, and problem-solving difficulties.
- These effects can persist for several hours after cannabis use.
Long-term Impairments
With frequent and long-term use, cannabis can cause persistent cognitive impairments. Studies show links between cannabis use and decreased IQ, memory, and cognitive control.
