“It’s difficult to explain how drug addiction develops over time. To many, it looks like the constant search for pleasure. But the pleasure derived from opioids like heroin or stimulants like cocaine declines with repeated use. What’s more, some addictive drugs, like nicotine, fail to produce any noticeable euphoria in regular users.
So what does explain the persistence of addiction? As an addiction researcher for the past 15 years, I look to the brain to understand how recreational use becomes compulsive, prompting people like you and me to make bad choices.”
