To the Editor: As William Grossman suggests in the conclusion of his report of "Adverse Reactions Associated with Cannabis Products in India" (Ann. Intern. Med. 70: 529, 1969), the medical community needs reliably researched data on the psychic and physiologic effects of marijuana. However, it should be spared biased and incomplete personal experiences like those of Dr. Grossman. He implies that marijuana use in the cases he observed was the cause of mental illness and fails to recognize it might as easily have been a symptom.
