Cocaine weighing in at 4.8g was discovered in the glovebox of a car involved in a road traffic collision in Hornsby Road, Grantham.
A Peugeot 206 being driven by Keia Dean Hull, 20, came off the road and hit a tree on February 16.
Magistrates heard how four bags of the class A drug were found in the glove compartment by officers. Hull had left the scene when police arrived but he was found nearby.
Chris Pye-Smith, defending, said: “The cocaine was for his personal use. He was planning a weekend away and got it for that purpose.”
Mr Pye-Smith added that Hull does not have drug dependency issues.
Hull, formerly of Grantham but now living in St Catherine’s, Lincoln, admitted possession of cocaine, as well as using a vehicle without insurance and driving otherwise than in accordance with a licence.
Magistrates heard how Hull was found to be in breach of a suspended sentence in March. The sentence was activated and he was sent to prison.
Mr Pye-Smith said: “Following his release, instead of coming back to Grantham he has broken links with this area and moved to Lincoln. He’s getting help with training to find employment, working with agencies.”
For driving with no insurance, Hull was fined £110 and his licence was endorsed with six penalty points, leaving him disqualified for six months under the totting up procedure. He was also ordered to pay a £20 victim surcharge and £50 towards costs.
For possession of a class A drug he was fined an additional £110. Magistrates ordered that the drugs be destroyed.
