Cannabis and Memory: Does THC Help or Hurt Cognitive Function?

Cannabis has complex effects on memory, with THC and CBD affecting cognitive function in different ways. While THC can impair short-term memory, some cannabinoids may offer neuroprotective benefits.

How THC Affects Memory

  • Short-term memory impairment – THC affects the hippocampus, the brain's memory center.
  • Alters recall and focus – High doses can make it harder to retain new information.
  • Tolerance effects – Long-term users may experience fewer memory issues over time.

Can CBD Improve Memory?

Unlike THC, CBD may help protect brain function by:

  • Reducing inflammation in the brain.
  • Supporting neurogenesis (growth of new brain cells).
  • Counteracting some of THC’s memory-related side effects.

Cannabis and Long-Term Brain Health

  • Some studies suggest high-THC use in adolescence may impact cognitive development.
  • Research is exploring CBD’s potential to slow neurodegenerative diseases like Alzheimer’s.

Key Takeaways

  • THC impairs short-term memory, especially at high doses.
  • CBD may have neuroprotective effects, supporting brain health.
  • Choosing the right strain and moderating THC use can help maintain cognitive function.

Cannabis users concerned about memory should explore CBD-dominant strains and lower THC doses.
