drug screens for recovering alcoholic presidents?

Physicians, airline pilots, and truckers who have been treated for alcoholism and chemical dependency are often required to have as many as 5 years or more of random (the call can come any day) weekly, witnessed (eyeball to urethra) urine screens for drugs and alcohol. I’ve personally known of doctors who, even after more than a decade of sobriety are mandated by the state licensing board to have these tests regularly.

Question: Should we hold a president to these same standards?

The requirements for president are laid out in the Constitution. Last I checked, drug testing wasn’t among them.
