Random drug testing on doctors

Lucian Leape MD is a public health public health professor at Harvard. The professor wants to subject doctors in America to some random and periodic drug tests. The professor is trying to help the patients by identifying those physicians who are impaired. Dr. Leape says "We have the responshibility to identify impaired doctors and bring them into treatment. And to protect patients in the process". There is a general surgeon named Jeffrey Parks who thinks the opposite of Lucian Leape and he does not believe it is the correct to put doctors through random drug tests. Dr. Jeffrey does believe they should not have impaired doctors working with patients but he does not think it is fair to do random drug test. He gives us examples to consider like a doctor going on vacation with his family or going to parties and drinking or smoking, things happen and they are not while they are working so it shouldnt really matter. He does not think its fair they decide to do this once and someone shows up the next day telling them they are forced to take a drug test that they will not pass because of a one night thing. He believes they should have the right to do what they want with their personl life and free time as long as they are not harming anyone. Dr. Jeffrey thinks that if a doctor is impaired it will b noticed by every1one else without making everyone take random drug tests. What will happen to those doctors that decide to party and come back to fail the drug test will they be getting their license taken away. It wont be fair to loose their job and mostly their entire life just because they decided to have a little fun while not at work. I also think like Dr. Jeffrey I believe that not just as a doctor but in any profession they should be able to decide what they want to do in their free time and not get themselves in a situation where they can loose everything they  have worked their entire life for. It wont be fair to loose years of studying their career, loosing their job and not being able to support their own family just because of something they decided to do one night that they were on vacation or just had the day off. Everyone should have the right to decide what to do with their life.
