A woman was throwing illegal drugs down a drain while police were speaking to a man after stopping their car.
Zena Lunness (34), of Hereward Road, Spalding, discarded cannabis and heroin on the afternoon of September 5, but police recovered the drugs and arrested her.
Lunness, of Hereward Way, Spalding, appeared before magistrates sitting in Grantham on Thursday for sentence on possession of cannabis, possession of heroin, three thefts from shops and failing to answer bail.
She pleaded guilty at previous hearings.
Lunness was given an 18-month supervision order with a nine-month drug rehabilitation requirement.
She must pay a £60 victim surcharge, £6 compensation to Spalding store Peacocks and £17.98 to the Lincolnshire Co-operative store at Whaplode.
Her solicitor, Mike Alexander, described Lunness as a young lady in the hold of a strong drug addiction.
During her interview with the probation service, she asked what was the point of it and wanted to go into custody – but she reengaged and admitted she knew what she had been doing was wrong.
Mr Alexander said: “She does want to stop using drugs.”
Marie Stace, prosecuting, said Lunness and another went into the One Stop Community Stores in Holbeach on April 27, selected two cans of lager and left without paying.
Lunness went to Peacocks on July 6, selected a pair of shorts and tried them against someone before leaving without paying. On August 13 she stole two Airwick fresheners worth a total of £17.98 from the Co-op.
