Researchers are constantly exploring how drugs affect our brains. In a recent interview with Cosmopolitan, Consultant Neurologist Dr. Naheed Khan, revealed the common side effects of several recreational drugs.

Khan said that damage to the body or brain due to drug use “can occur at any time from the first dose to that after repeated use.”

“There is nothing that can predict what and when will happen in any one individual,” he added.
