It's the Internets:
President Barack Obama left many viewers with the impression that he was stoned on drugs during his interview broadcast Friday night on NBC as part of the network’s coverage of the Sochi Olympics opening ceremony. The session with Bob Costas was taped Thursday by remote with Obama at the White House and Costas in Sochi, Russia.
Parry commented: “Uh, I am pretty sure President Obama is high in this NBC sports interview.”
...Parry was not alone in his observation. Twitter lit up with user’s astonishment at Obama’s stoned appearance in the interview.
Obama was a stoner in high school and college to the point he reportedly sucked the last wisp of pot smoke from the interior roof of cars when he and the choom gang, as he and his druggie friends called themselves, got high...
To be fair, I'm pretty sure Reagan was a stoner, too.
