What is the Most Weed Smoked by a Person?

It is extremely difficult to verify who has the most joints smoked ever. But a record for that has already been logged in the Guinness Book for World Records. So, who is it? It is not Snoop Dogg, even though he probably is a legitimate candidate. According to official documents, the record-holder for the most weed smoked is cannabis legend Irvin Rosenfeld.


Back in 2006, medical user Irvin Rosenfeld was added to the Guinness Book for World Records for having smoked 115 blunts in a single day. In 2014, he was also able to prove to the Guinness team that he is the person who has “the most marijuana consumed.” Is it even possible to count how many joints someone has smoked over their lifetime? In Rosenfeld’s case it was easier to conclude a specific number, partly because he was once part of the U.S. Federal Medical Cannabis patients program.

Cannabis Patient Irvin Rosenfeld Was Sponsored Free Weed by the Government for Decades 

Irvin Rosenfeld enrolled in the U.S. government-sponsored Experimental New Drug Research Program back in 1982. The program stayed active until 1992. It is said that Rosenfeld continued to receive free joints every day by the government even when the program stopped. If counted all the joints he received thanks to the feds from 1982 and onwards over the next three decades, we’ll get a figure of more than 120,000 joints smoked. Of course, there probably are millions of other people who’ve consumed the same amount or even more weed than that over their lifetime, but only Irvin Rosenfeld has been able to provide paperwork that attests to how much he has consumed of the green herb. 

The reason why he was enrolled in the government program was that Mr. Rosenfeld was suffering from a rare form of bone cancer. As such, he was entitled to a monthly supplement of 300 joints.

“I don’t know that I’ve broken a record, but I’ve certainly set one. No one else in the world can document having smoked 115,000 cannabis cigarettes - let alone the ones I smoked before that,” said Rosenfeld at the time. “I’m living proof that medical cannabis is real medicine. We need to get medicine in the hands of patients who really need it,” he added. 

Rosenfeld has also written a book about his experience with cannabis and government. It’s an all-telling title: My Medicine, How I Convinced the U.S. government to Provide My Marijuana and Helped Launch a National Movement.  

Indeed, cannabis has helped Irvin Rosenfeld to survive cancer. The irony here is, the government was helping him out with free cannabis medicine during a time when it maintained a harsh policy on cannabis. Even now in 2025, marijuana is still enlisted as a Schedule I substance along with way more stronger drugs like heroin and LSD.
