I want to know the answer to the following question:
In what year did the American Medical Association approve amphetamine for medical use?
All the background I'm provided with is that "It received approval as a New and Nonofficial Remedy from the American Medical Association for these uses in 1937 and remained in common use for depression until the development of tricyclic antidepressants in the 1960s.". Is that enough to answer the question?
Answer: yes
