The research, conducted by electronic cigarette retailer ECigaretteDirect.co.uk, found 30% of those polled spent more than an hour each day getting a nicotine hit.
This equates to more than half a working day per week or 200 hours - or five typical working weeks - per year.
More than half (56%) of those surveyed said they spent between 20 to 60 minutes each day smoking, with 13% taking less than 20 minutes for their cigarette breaks.
The poll also found the actual number of cigarettes consumed during working hours varied widely, with the majority of smokers (41%) puffing away on between 10 and 20 cigarettes a day.
Just under one fifth of smokers (17%) consumed between 20-30 a day, another fifth puffed on between five and ten cigarettes, with 8% working their way through more than 30.
