Prince Harry has spoken of 'going wild' as he chatted with a Hollywood star about their own drugs and alcohol problems.
The Duke of Sussex, 36, was speaking on actor Dax Shepard's 'Armchair Expert' mental health podcast when he made the remarks.
Harry was quizzing the star - who is married to Frozen actress Kristen Bell - about the American's substance use in high school.
The Royal asked him about Shepard's 'awareness' of what sparked his path towards drugs as a teenager.
Harry told him 'For you it was your upbringing and everything that happened to you - the trauma, pain and suffering.Insurance Loans Mortgage Attorney Credit Lawyer
'All of a sudden you find yourself doing a s***load of drugs and partying hard.
'Look how many other people do that as well. They wouldn’t have the awareness at the time.
'I certainly wouldn’t have had the awareness when I was going wild.
'It’s like why am I actually doing this? In the moment its like, this is fun. I’m in my 20s - it’s what you’re supposed to do.'

Harry himself has been linked to smoking cannabis and drinking.
A recent Channel 5 documentary called Prince Harry: The Troubled Prince featured broadcaster Daisy McAndrew.
She told the programme: "You can really understand how a lonely, privileged unhappy Prince would end up drinking and partying and taking cannabis to fill those hours and hang out with people he thought really liked or even loved him."
Prince Charles is known to have taken the young Duke aged 16 to a residential centre for drug users for a visit after finding out.
Reformed users at Peckham's Featherstone Lodge warned him their addictions had started with drinking alcohol and smoking cannabis.
Harry's comments came on Shepard's podcast where he bared his soul on his unhappiness in the Royal family.
He also said he was so desperate to hide his relationship with Meghan when she stayed at Kensington Palace for the first time that they went 'incognito' to the supermarket and 'pretended we didn't know each other', texting shopping list items from different aisles.
Speaking with a slight American twang to his British accent, Harry said his life was like The Truman Show - when Jim Carrey's character discovers his life is a TV drama - as he discussed his emotional state and how he started therapy after Meghan 'saw he was angry'.

Harry admitted his life was like The Truman Show starring Jim Carrey and Natascha McElhone was a huge hit, nominated for three Oscars.
The blockbuster follows a man who is unaware that he is living in a reality show, played by Jim Carrey.
Truman has a job in the insurance business and a wife, but he eventually notices that his environment is not what it seems to be and that everyone in the show is an actor apart from him.
Once he cottons on he is repeatedly thwarted until he manages to escape, saying his catchphrase: 'In case I don't see you... good afternoon, good evening, and good night', bowing to his audience and walking off set to cheers from viewers around the globe.
Shephard asked him what it's like being in a 'tiny group' of royals 'watched by millions', to which Harry replied: 'Yep, it's a mix between The Truman Show and living in a zoo'.
When asked if he felt 'in a cage' while in royal duties, he said: 'It's the job right? Grin and bear it. Get on with it. I was in my early twenties and I was thinking I don't want this job, I don't want to be here. I don't want to be doing this. Look what it did to my mum, how am I ever going to settle down and have a wife and family when I know it's going to happen again'.
He added that his frame of mind was: 'I've seen behind the curtain, I've seen the business model and seen how this whole thing works and I don't want to be part of this', before revealing he had therapy after meeting Meghan, which 'burst' a bubble and he decided to 'stop complaining'.
He added: 'So living here (in Los Angeles) now I can actually lift my head and I feel different, my shoulders have dropped, so have hers, you can walk around feeling a little bit more free, I can take Archie on the back of my bicycle, I would never have had the chance to do that.'
The royal is understood to have met his friend Shepard more than a decade ago and agreed to support his popular podcast about mental health and 'the messiness of being human', including addiction. Harry's appearance may also be linked to the podcast's move to Spotify in July because the Sussexes have also signed a multi-million dollar deal with the streaming firm.
Harry, who is currently living in his $14million Californian mansion with his wife and son, said he was born into extraordinary privilege but hinted that he believes this has changed since he quit with Meghan last year, comparing it to Oprah Winfrey's humble beginnings. He said: 'I truly believe you can move along the spectrum as well, wherever you were born you may start in one place but that will change over time'.
