Ever wonder what conditions people are treating with medical marijuana? Jimmy Kimmel hit the Hollywood Walk of Fame to ask passersby if they had prescriptions and what they had them for.

"The condition is children, jobs, life," said one patient.

"I guess you need one, huh?" said another who was caught off-guard by the question.

"No, but my son does," a middle-aged man said. Why does he have one? "To buy his dad medical marijuana."

The bogus prescriptions show that history is repeating itself. During alcohol prohibition in America (1920-1933), the United States Treasury Department allowed physicians to prescribe liquor to patients for conditions including cancer, indigestion, asthma, snakebites and old age.

According to Daniel Okrent - author of "Last Call: The Rise and Fall of Prohibition" (2011) - doctors in the 1920s could write as many 100 prescriptions for liquor per month, charging $3 for the "medicine." And physicians weren't the only ones doing it. Dentists and even veterinarians were also allowed to prescribe alcohol for medicinal use. After receiving their scripts, "patients" had to pay an additional $3-4 to get their script filled at the drugstore, some of which were saloons that rebranded themselves as drugstores even though they still only sold liquor.

No wonder contemporary humorist Will Rogers once quipped, "Prohibition is better than no liquor at all." Check out the full segment from Jimmy Kimmel for a few more laughs at the absurdity of marijuana prohibition.
