It's well-known that many people use marijuana to help sleep at night. But you may be surprised to find out just how many use cannabis for that purpose.

A new study conducted by Sleep Cycle, an alarm clock app, found that 14 percent of American adults use marijuana to help sleep at night. That percentage is the same amount as the number of people who eat milk and cookies to fall asleep, and higher than the amount of people who use Nyquil or Tylenol PM to fall sleep (12 percent) or alcohol (10 percent). 

The only two other sleep aids that were used more than marijuana were tea (21 percent) and melatonin (15 percent). Perhaps most encouraging about the study was that Ambien and other sleep medications came in last with only nine percent.

The survey also delved into the politics behind sleep. 23 percent of respondents said they would sleep better if President Barack Obama were still in office. Nine percent said they would sleep better if Bernie Sanders were president, while respondents also said they'd sleep more soundly if Hillary Clinton (six percent), Oprah Winfrey (five percent) or J.K. Rowling (3 percent) were president. (NOTE: Since J.K. Rowling was not born a naturalized citizen of the United States, she is not eligible to become president.) 32 percent of respondents said their sleep is unaffected by whoever's in the Oval Office.
