HUNTER Biden admits he smoked Parmesan cheese after mistaking it for crack cocaine at the height of his addiction.
The US President's son, 51, revealed the extent of his drug problem in a warts-and-all interview with CBS Sunday Morning.
He said: "I spent more time on my hands and knees picking through rugs smoking anything that resembled crack cocaine.
"I probably smoked more Parmesan cheese than anyone - than anyone you know Tracy."
He then told interviewer Tracy Smith: "I once went 13 days without sleeping and smoking crack and drinking vodka exclusively throughout that entire time."
Hunter said that he "never" thought his dad Joe would "give up on me."
The president's second son, a lobbyist and Yale-trained lawyer, said he was "cooperating completely" with a DOJ probe into his finances.
He added: "And I am absolutely certain, 100% certain that at the end of the investigation, that I will be cleared of any wrongdoing."
Hunter also addressed reports that a laptop dropped off at a repair shop, which was handed over to the FBI, contained photos of him taking drugs and detailed his business dealings in Ukraine.
He said: "Certainly, there could be a laptop out there that was stolen from me.
"It could be that I was hacked, it could be that it was Russian intelligence. It could be that it was stolen from me.
The laptop is also reported to contain a 12-minute video that appears to show Hunter smoking crack while engaged in a sex act with an unidentified woman.
The New York Post also published a "smoking-gun" email that it alleged reveals how Hunter introduced his father Joe to a Ukrainian businessman, Vadym Pozharskyi, when Biden Snr was Vice President.
Both Bidens have denied any wrongdoing, and Joe's campaign denied the alleged meeting with Burisma boss Vadym Pozharskyi ever occurred.

Hunter, who is promoting his book Beautiful Things, opened up about addiction in the two new interviews with CBS - the first of which aired this morning.
The 51-year-old told how his father one day "ditched his Secret Service" while VP and confronted him about his substance abuse insisting he seek help.
On his struggles, he said: "You would wake up some mornings – I shouldn't even say some mornings, 'cause you slept for, like, 15 minutes at a time – and be looking for crack, and just smoke whatever was there?"
