Absolutely true but it's worth noting this has only been done for a small fraction of marijuana crimes, and as far as I know not at all through the backdoor method commonly used (by all administrations) where they just prosecute otherwise legal gun ownership as "owned a gun plus owned weed" and backdoor it as a gun crime.
