Josh Brolin sleeps with nicotine pouches in his mouth

Josh told the WTF with Marc Maron podcast: "I have a pouch in my lip, and I'm not f****** lying, 24 hours a day. Then I started taking them out and putting them on the bedside table."

Imitating a chewing sound, the 'Dune' star added: "My wife would hear this in the middle of the night. I don't even know I'm doing it, I'm asleep."

Josh explained that he would rather use nicotine lozenges but had to stop as they had a devastating impact on his oral hygiene.

He said: "They go away in two seconds, but they taste like gasoline, and there's a punch to them.

"But I used to keep them up between my gum and my tooth line. I got seven cavities. That's why I switched to (pouches). There's a ton of sugar (in lozenges)."

Brolin's need for the pouches is so great they he even ended up using a dubious variety whilst filming a project in the Middle East.

The 'No Country for Old Men' actor recalled: "We're in Jordan. And (this guy) comes up to me, and he says, 'I have some.' And it has a skull and crossbones on the top... And it's 40 milligram packets. And I said, 'I can't do that.'

"And then one day, I start running out, and I haven't quite run out, I probably have four or five more tins (of my usual pouches left). And I have his thing in my pocket, and I'm running back from the gym."

Josh added: "I stick the thing in my mouth for no more, and I swear to God on my kids, for no more than 20 seconds, and I had to cancel dinner that night. I literally was s******* my brains out."
