re: #420 Timothy Watson
There’s a question on the standard background check form asking if, “Are you an unlawful user of, or addicted to, marijuana or any depressant, stimulant, narcotic drug, or any other controlled substance?”.
Seriously, that’s their paper shield.
Two of the questions on the form to apply for a US visa ask if the applicant has ever been engaged in terrorism or belonged to a terrorist group, and if the applicant has ever been involved with drug smuggling or human trafficking.
