The president's brother Frank, children Hunter and Ashley, his niece Caroline and his late son's widow who likewise became Hunter's lover, Hallie, have all undergone addiction problems and had spells in treatment centers – some at the orders of a judge.
In text messages to Hunter, Joe even referred to his son's obsession as a 'disease from mommy and me.'
The revelations cast a new particular light on the president's previous vendetta against drugs, denouncing George Bush Sr's 1980s War on Drugs for being 'not tough enough' and writing punitive laws with severe sentences for drug crimes when he was head of the Senate Judiciary Committee in the late 1980s and early 1990s.
Joe Biden himself is reportedly a teetotaler, after seeing the results of alcoholism on his beloved uncle who he lived with as a kid, according to an October 2020 New York Times profile.
The president has previously blamed the truck driver involved in the 1972 accident that killed his first wife and daughter, for being drunk at the time, even though the driver was not charged with a DUI and police found no evidence of drunk driving.
The President's stubborn son became the poster child for drug addiction's ruinous effects, as his descending spiral into crack smoking and sordid affairs with prostitutes was exposed last year when pictures and messages from his abandoned laptop fell into the media's control.
Though texts on the laptop further show that Hallie Biden, his brother Beau's widow who became his lover after Beau died of brain cancer in 2015, has been to rehab four times, costing more than $100,000, some of it allegedly paid for by Joe Biden.
Amid an argument in December 2018 in their rocky and controversial relationship, Hunter texted Hallie saying: 'You didn't stay longer than 10 days away from family at any one of the 4 times you went to rehab.'
Throughout the conversation Hunter discussed which rehab center he will be attending, and revealed that the president spent $45,000 on a ten-day rehab stay for Hallie.
'It's 3 Months because you have told me and anyone who would listen that I need long term It's closer. D more accessible to my children and dad then Caron [a Pennsylvania and Florida rehab group] is by far,' he wrote.
'It's much less than the $57,000 I paid for you at [upscale Malibu, California rehab] Passages ($5,700 per day) or the $45,000 Dad paid at Caron (4500 per day you stayed). You don't [have] to help me with a dime.'
