In a study of nearly 9,000 Britons whose memory and mental function were tested at age 50, researchers found that those who had used illegal drugs as recently as in their 40s did just as well or slightly better on the tests than peers who had never used drugs.
When the participants were surveyed at age 42 about current or past drug use, marijuana was by far the most common indulgence: six percent said they had used it in the past year, while one-quarter said they had ever used it.
