Take a look at the following thread:
There are some posts from June and September 2018 discussing denials of Global Entry due to use of marijuana.
Result of an appeal is reported in the
Anyone Ever Get Turned Down for Global Entry? thread:

I cannot conclude otherwise from my experience than if an officer asks if you have ever used an illegal drug, the answer you must give is no.
After 5 years, a reapplication, another ombudsman rejection, a FOIA response pretending that a file to which the ombudsman's office referred in their rejection did not exist, and a FOIA appeal that demonstrated the government was lying about the nonexistence of the file in the FOIA response, I now have the answer.
Admission of any previous marijuana use, even though it is currently legal where I live, will disqualify you for life from Global Entry under the "strict program requirements" banner.
If the officer asks you this question, you are officially screwed because to obtain Global Entry you would be forced to make a false statement to a federal agent. The questions they choose to ask you seem to be at their discretion, so, perhaps cutting your hair and wearing a suit to your interview like it's still the 1950s would be a safe bet.
