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.
But Halpern agreed that the current results do not rule out the possibility of lasting negative cognitive effects from heavy, prolonged drug use.
There are, of course, other reasons to avoid illegal drugs. As an example, Halpern noted that cocaine can trigger a stroke. And one of the possible consequences of a stroke is long-term cognitive impairment.
