Police raided a house in Sedgebrook and found a quantity of cannabis in a Kinder Egg on a bedside table.
Brett White, 40, admitted possessing cannabis and was fined £215 with £85 costs and a £15 victim surcharge by Grantham magistrates.
Prosecutor Jim Clare told the court that White admitted to police that he smoked cannabis and it was for his personal use.
Bill Fraser, defending, said White had smoked cannabis for a number of years.
Mr Fraser said: “He finds it calms him down and relaxes him.
“He has a heart condition and it keeps him calm and allows him to chill out a bit.”
The court heard that White had recently got a job with Centrebus doing repairs, but had got into a lot of debt over the last seven years.
