President Obama is on record of admitting his past illegal use of illicit marijuana and the public has even seen photos of him with joint in hand.
Recognizing that had he been caught at that time he would not be President today, but rather serving time in prision, and in order for him not to be regarded by the public as unethical, immoral, and hypocritical, the President himself must either resign from office or take immediate and public action to cease forever the Federal attacks against all users of cannabis by rescheduling it and by announcing his intention to allow states, and the people, respectively, to enact and their own laws pertaining to cannabis.
