I know that positions that deal with highly sensitive information do require drug testings. FBI specially asks you questions before you even see their job listings. FAA and a few others require as well. However, I've been applying to jobs that are more research/analyst positions for SEC, Treasury dept, etc., and I was wondering if the these would require such testings as well? Also, if the job posting does not specify a drug test, if it is common that they will still pursue the test.
