Robert F. Kennedy Jr. says antidepressants are harder to quit than heroin – is he right?

Robert F. Kennedy Jr. has been sworn in as the US health and human services secretary, despite saying a few things that raised eyebrows during his confirmation hearing.

He was referring specifically to the current generation of antidepressants called selective serotonin reuptake inhibitors, or SSRIs.
