President Donald Trump's name is the most popular code word for buying and selling methamphetamine.

When people buy and sell drugs online, they use different types of code names, including the names of celebrities.

Donald Trump's name just happens to be the most popular for meth, according to Drugs Decoded, a study by Addictions.com.

The study surveyed more than 2,000 people to learn how Americans talk about drugs and what words they use when buying them.

But according to Attn:, the study isn't accurate because it was only done through an online survey and it wasn't peer-reviewed.

The data scientist who conducted the survey told the outlet that there were limitations to the study.

'While we were hoping to get larger responses from each of those individual drug users, unfortunately this was the most that we could get via this methodology, Logan Freedman said.

'It's still just about enough that it was worth highlighting, but again, we always would like to have a much larger sample size.'

Researchers manually went through the code name responses and identified the words people identified most in the survey.

Though Donald Trump is the most popular code for meth, he isn't the only president on the list.

Richard Nixon, the 37th US President, is the most popular celebrity code for marijuana.

Former Speaker of the House of Representatives Nancy Pelosi is the code for LSD, Founding Father Benjamin Franklin is code for Benzodiazepines and the late leader of North Korea, Kim Jong-Il is code for crack.

Malcolm X is the code for ecstasy, Lady Gaga is code for cocaine, Chuck Norris for heroin, Chris Farley for opiates, and the video game character Mario is code for mushrooms.

The study also found the food code names for drugs, including the fact that meth's food code is coffee, marijuana's is pizza, cocaine's is sugar and crack's is crackers.

Tomato sauce is the code for heroin, donuts is the code for opiates, Cheez-its is the code for mushrooms, Cadbury is the code for Benzodiazepines and candy bar is code for ecstasy.

LSD did not have a food code word, according to the study.

According to the study, distributors use code to avoid legal issues, particularly if the discussion of the sale is happening online or on the phone.

'More than a third of participants between the ages of 18 and 29 told us they’d been denied drugs because they didn’t use the proper code words,' the study said.
