Thats not true. From the article YOU posted:
"Murthy isn’t the first surgeon general to wade into the debate about marijuana and drug policy. In 1993, Joycelyn Elders, the surgeon general under the Clinton administration, said the U.S. should seriously consider legalizing drugs. “I do feel we’d markedly reduce our crime rate if drugs were legalized,” she said at the time. Since leaving office, Elders has actively campaigned for states to pass medical marijuana laws."

"The evidence is overwhelming that marijuana can relieve certain types of pain, nausea, vomiting and other symptoms caused by such illnesses as multiple sclerosis, cancer and AIDS -- or by the harsh drugs sometimes used to treat them. And it can do so with remarkable safety. Indeed, marijuana is less toxic than many of the drugs that physicians prescribe every day."
