On his latest episode of The Joe Rogan Experience, Mel Gibson claimed three of his friends all had stage four cancer, and what he has described as ‘some serious stuff going on.’

The actor claimed they took ivermectin and fenbendazole – drugs that are used to treat infections such as roundworms and threadworms.

He then said, after taking them, ‘they don’t have cancer right now.’

‘This stuff works, man,’ he added.

Some research suggests that fenbendazole can stop the growth of cancer cells – however, experts have said that despite early research looking good, there are some serious side effects.

Gibson said: ‘I don’t believe that there is anything that can afflict mankind that hasn’t got a natural cure for it. It just makes sense to me.

‘I couldn’t prove that, but I just believe that. There’s got to be something that cures things.’

Referring to both drugs mentioned, Rogan added: ‘This stuff does work, which is strange because it’s not profit.’

Rogan added: ‘When you hear about things that are demonized and they turn out to be effective, you always wonder, “What is going on here? How have our medical institutions failed us so that things that do cure you are not promoted because they’re not profitable?”‘

Dr Susanne Arnold, associate director for clinical translation at the Markey Cancer Center in Kentucky, told The Associated Press in 2024 that while yes, there have been pre-clinical studies exploring ivermectin and similar drugs that could slow cancer cell growth in labs, this isn’t the same as proving that the drugs would work in humans.

She said: ‘I know of no reports of clinical trials that yielded successful results in humans with cancer.’
