"Tobacco, properly used may, in some cases, 

 undoubtedly be made a mental hygienic." 



Mann (Brit. Med. Journal, 1908, V. II, p.

 men if they choose to smoke can do so within 

 certain limits without injury to health. Some 

 men can exceed such limits with apparent im- 

 punity. The extent of the limitation must be 

 determined by each man for himself."
