Did Barack Obama do cocaine in high school?

Answer 1

Mr. Obama has admitted that he did try cocaine, while going through a difficult period of time during high school and his first year of college. Mostly, he used marijuana, but ultimately, he worked through the issues that were bothering him, and he decided that being involved, even casually, with drugs was not the kind of life he wanted. He stopped using them, focused on his education, and never went back to using any illegal substances.

Answer 2

Yes.

As an adult Obama admitted that during high school he used marijuana, cocaine and alcohol, which he described at the 2008 Civil Forum on the Presidency as his greatest moral failure.
Yes he did. He smoked pot too. He said his grades improved when he quit drugs.
