Physicians should be consistent role models, avoiding tobacco and alcohol to effectively counsel patients against their use.

Original passage

Many come under the physician's care who are ruining soul and body by the use of tobacco or intoxicating drink. The physician who is true to his responsibility must point out to these patients the cause of their suffering. But if he himself is a user of tobacco or intoxicants, what weight will be given to his words? With the consciousness of his own indulgence before him, will he not hesitate to point out the plague spot in the life of his patient? While using these things himself, how can he convince the youth of their injurious effects?
