Funny but true story. Years ago I applied for the FBI and went through 2 1/2 years of tests, psycological, interviews, polygraph, etc, before I became impatient and finally lost interest and bowed out. Anyways, I will never forget sitting in a room and being asked to once again complete the application for field agent, as the agent speaking said, "it is very often that we have applicants fail the polygraph because they state they have never taken an illegal substance, yet in fact they have and it ultimately gets revealed during a polygraph test, resulting in disqualification from the process, so here is your chance to come clean". He than stated, "The FBI does not hold it against applicants if they have smoked marijuana, as it would be hypocritical as our Commander in Chief has admited to smoking marijuana, but of course he didn't inhale". LOL
