When extrapolated out, that would make it the biggest dip in people smoking in a decade.
As well as that, more than 40 percent of respondents said they'd stopped as a result of the pandemic, not least because smokers are thought to be at greater risk of having severe symptoms after falling victim to the virus.
The survey discovered more younger people are quitting, too. That's definitely good news.
Seventeen percent of people aged between 17 and 29 years old have stopped smoking during the ongoing pandemic.
Added to that, five percent of over 50s have knocked fags on the head.
This news comes as ASH launches a new campaign to get people to stop smoking, as the UK is still home to seven million smokers.
They've been instrumental in helping bring forward legislation that makes life more difficult for tobacco companies, as well as helping to bring down smoking rates.
Most cigarette advertising and sponsorship was banned in 2003 and shops were banned from displaying tobacco behind counters in 2015.
All cigarette packaging must now be standardised without any branding, and menthol cigarettes were the most recent thing to go.
Hazel Cheeseman, the directory of policy at ASH, told MailOnline: "We don't know for sure why so many people are giving up smoking. But we feel the threat of coronavirus has motivated people to do things to improve their health."
One reason so many young people have quit could be that they've been at home with their families, and therefore unable to hide their habit.
A disruption in people's social lives could also be responsible for stopping social smokers from developing or indulging the habit.
The analysis came from a survey of 10,251 people conducted by YouGov and measured responses between 15 April - the peak of the outbreak - until 20 June.
They were then extrapolated out using estimates from the Office for National Statistics.
Deborah Arnott, the ASH charity chief executive, said that it's time to 'wake up and decide' to stop smoking.
