How can alcohol, tobacco, or drug use lead to memory loss?

ANSWER

Excessive alcohol use has long been recognized as a cause of memory loss.

Smoking harms memory by reducing the amount of oxygen that gets to the brain. Studies have shown that people who smoke find it more difficult to put faces with names than do non-smokers. Illicit drugs can change chemicals in the brain that can make it hard to recall memories.
