I updated the post. He was taking various things. I don't think heroin would work well for treating adhd on it's own. Don't bother

Robert F. Kennedy Jr. once claimed that using narcotics made him do better in school.
In the midst of his presidential campaign, the independent candidate discussed his history of drug use and addiction during a July appearance on the “Shawn Ryan Show” podcast.
Kennedy recalled having his first encounters with drugs the summer after his father, Sen. Robert F. Kennedy, was assassinated during his Democratic campaign for president in 1968.
After quickly progressing from recreational LSD to regular use of cocaine and heroin, Donald Trump’s choice to lead the Department of Health and Human Services said, he found that being under the influence actually improved his studies.
“I did very, very poorly in school until I started doing narcotics,” he said on the podcast. “Then I went to the top of my class because my mind was so restless and turbulent and I could not sit still.”
Noting he’d likely be diagnosed with ADHD these days, Kennedy said he looks back at his drug use as a form of self-medicating.
“Suddenly I could sit still, and I could read and I could concentrate,” he told Ryan. “I could listen to what people were saying, and things made sense to me.”
