Toronto's mayor Rob Ford has given a candid interview in which he admits he was "born an alcoholic".
Speaking on Canadian television, Mr Ford also said his drug use encompassed "everything you can think of", including marijuana and magic mushrooms.
Embattled Toronto mayor Rob Ford has told Canadian media he has used "every drug you can probably think of" as he returned to work after a rehab stint.
He also claimed to have been "born an alcoholic" but refused to say whether he would step down if he relapsed.
Toronto native Ford will be seeking re-election in October later this year, saying it was "up to voters" to decide if he stays or goes.
Ford first admitted smoking crack cocaine in November last year after a video emerged of him using a crack pipe and began a string of scandals which saw him stripped of any real mayoral powers.
Rob Ford, the controversial mayor of Toronto, is to "go get help" for "substance abuse" problems, his lawyer has said.
Local paper the Toronto Sun quotes Mr Ford as saying he is "ready to take a break" from campaigning for re-election as mayor in order to seek help.
His lawyer, Dennis Morris told the Associated Press:
"He acknowledges he has a substance abuse problem and he wants to do something about it."
Toronto Mayor Rob Ford has put his name on the ballot to run for another term, defying repeated calls for him to step down after admitting he smoked crack cocaine.
Ford was the first candidate to show up at City Hall when registration opened on Thursday for the city's municipal election on October 27.
Toronto mayor Rob Ford may have offered $5,000 (£2,860) and a car to men trying to sell a video that allegedly shows him smoking crack cocaine, police documents published in Canada's National Post show.
Police notes on a recorded phone conversation between two suspected gang members reportedly showed that Mr Ford was aware of the video's existence and wanted to buy it.
The men rejected the mayor's apparent offer and planned on asking for $150,000 (£85,850), according to a police document released by an Ontario Superior court judge.
Mr Ford, who admitted that he smoked crack in a "drunken stupor" around a year ago, has denied the claims.
Toronto's scandal-hit mayor Rob Ford has suggested that his past misdemeanours may be due to the fact that he "hung around with the wrong company".
In an interview with Canadian broadcaster CP24, he admitted again to having taken crack "maybe once" and to experimenting with party drugs in his youth:
Toronto's beleaguered mayor Rob Ford has told NBC's Today show: "They are not going to find another Rob Ford".
Ford, who eventually admitted smoking crack cocaine after a video surfaced of him doing it, told co-anchor Matt Lauer: "I can't even barely remember it. I was very, very inebriated".
Asked why he initially denied the allegations, Ford said he was asked by reporters, "'Do I use crack cocaine?' No, I don't use crack cocaine. No. Have I tried crack cocaine? Yes, I've tried crack cocaine".
He added: "I've embarrassed, not just myself, my family, my friends, my supporters, the whole city. I take full responsibility for that".
Ford, who faces an electoral race next year, said he "absolutely" still wants to be Toronto mayor, stating: "October 27 - let the people decide".
Toronto Mayor Rob Ford has hit another setback after he pushed over a woman councillor during a heated council meeting.
He charged around the chamber after arguing with members of the public, before the speaker asked security to clear the chamber and a recess was called. Members of the public then chanted "Shame! Shame!" at the mayor.
The Mayor admits he has made mistakes, but says he remains ambitious, adding: "Have I had my outbursts in the past? Absolutely. But you know what, I'm only human. I've made mistakes. I've apologised."And he still covets the job.
"Yes, one day I do want to run for prime minister," he said.
Video shows Ford moving around the gallery and at one point he knocks over a woman councillor before picking her back up.
