Puff, puff, pass the paperwork.

About 9.74% of Americans have gone to work under the influence of marijuana, according to a survey conducted by SurveyMonkey for Mashable. About 534 Americans shared their marijuana and prescription drug taking habits when it comes to the workplace. The sample was gathered using SurveyMonkey Audience.

Of that group, a whopping 80.77% admit to getting their hands on the drug illegally. According to Mother Jones, an estimated 22 million pounds of marijuana is grown each year in the U.S. The drug is legal to purchase recreationally in Washington and Colorado, while it's legal for medicinal purposes in 23 states and Washington, D.C.

Prescription drug takers were much more common, with 28.28% of people saying they've gone to work after taking prescribed medication. However, about 7.28% say they took these drugs for recreational purposes, rather than medicinal purposes. Unlike the marijuana users, about 95.36% legally acquired the drugs through a doctor's prescription.

Considering most workplaces in the U.S. do not require their employees to take a drug test, secret potheads and recreational drug users can continue to go unnoticed. However, that doesn't mean you can't lose your job — or get so stoned that you don't even know if you still have a job.
