It would seem reasonable convicts would be pardoned.

Y'know, I can understand releasing the people charged with possesion or consumption.
Problem is, many drug related offenses are accompanied by 'other' crimes.
Marijuana is seldomly the sole reason for a prison sentence anymore.

Even people imprisoned from past laws have 'other' things keeping them from being released.

ACLU report.
'Just under half of the million and a half annual arrests for non-violent drug violations are for marijuana. Because the vast majority of drug arrests are for non-violent offenses

Okay but most non-violent marijuana arrests do not result in prison time.
Hence, not convicts and not pardoned.

There is a big difference between an offender and a convict.
There is a big difference between records expunged and a pardon.

It’s true that police, prosecutors, and judges continue to punish people harshly for nothing more than drug possession. Drug offenses still account for the incarceration of almost half a million people, and nonviolent drug convictions remain a defining feature of the federal prison system.
