A systematic review published today in the scientific journal Addiction has found that cannabis use leads to acute cognitive impairments that may continue beyond the period of intoxication. This Canadian-led meta-review (review of reviews) merged the findings of 10 meta-analyses representing more than 43,000 participants.
The study found that cannabis intoxication leads to small to moderate cognitive impairments in areas including

• making decisions,
  
• suppressing inappropriate responses,
  
• learning through reading and listening,
  
• the ability to remember what one reads or hears, and
  
• the time needed to complete a mental task.
  

These and other acute impairments mirror the residual effects documented for cannabis use, suggesting that the damaging effects of cannabis begin while it is being consumed and persist beyond that period.
