Presidential pardons are federal only; most convictions for drug crimes are state-level and wouldn't be affected. Presumably some could be, but there are better paths to "war on drugs" reform, including changing the federal enforcement priorities while encouraging Congress to change the relevant laws.
A president could hypothetically pardon "all persons convicted of drug-related offenses," without or without a time limit (he could limit it to the last 15 years or whatever). It'd just not be incredibly useful (because so many of the prosecutions are done by the states), and would involve a PR nightmare of pushback unless done in the last few hours before leaving office.
I want Bannon and any of his other pardoned cronies who've been active recently to be subpoenaed for the Senate impeachment trial. Oh look, immunity from federal prosecution... so, no invoking the 5th amendment... speak up or be guilty of contempt of court, and watch out for perjury.
