Obama is known to have used Cannabis. He is now a president. He ran, and won two times now. Clearly, he believes a person could've had used Cannabis for recreation and remain suitable to run and hold public office. Yet he denies this to others who simply did not get lucky as he did. He either unjustly remains in office - or is denying justice to other citizens who simply did not get lucky.
Pardon all Cannabis-related convictions. If possible - finally change your stance on Cannabis legalization and Federal stance - as both surveys and States legislation shows the tide on this issue has already changed.
There's talk of people being stuck on "wrong side of history". Don't be one of them, mr President.
