Apparently Snoop Dogg isn’t the only person to have smoked marijuana in the White House. According to John F. Kennedy: A Biography, President Kennedy relieved the symptoms of severe back pain and Addison’s disease, which is a rare endocrine disorder, by using medicinal marijuana. From the book:
On the evening of July 16, 1962, according to [Washington Post executive] Jim Truitt, Kennedy and Mary Meyer smoked marijuana together…The president smoked three of the six joints Mary brought to him. At first he felt no effects. Then he closed his eyes and refused a fourth joint. ‘Suppose the Russians did something now,’ he said.
Addison’s disease causes the adrenal glands to produce insufficient steroid hormones and its symptoms include low blood pressure, weakness, coma and severe abdominal pain.
