Los Angeles ( CNN ) -- Lindsay Lohan must report to jail by June 17 to begin serving a 120-day sentence for a necklace theft charge , a judge ordered Wednesday . After her sentencing , the court released a probation report that said the actress `` appears to be continuing to struggle with substance abuse issues . '' Lohan was not at the hearing , but her lawyer entered a no contest plea -- equivalent to a guilty plea -- to the misdemeanor theft charge on her behalf Wednesday morning . `` I am glad to be able to put this past me and move on with my life and my career , '' Lohan said in a written statement released Wednesday afternoon . `` I support the judge 's decision and hold myself accountable for being in this situation . '' Early release formulas , required by a federal order to reduce jail overcrowding , will likely reduce the sentence to about 14 days in jail , Los Angeles County Sheriff spokesman Steve Whitmore said after the hearing . `` Because of budget constraints and because we 're under a federal consent decree that requires us to curb our overcrowding situation , nonviolent offenders , lesser crimes , get 20 % of their sentence , '' Whitmore said . Los Angeles County Superior Court Judge Stephanie Sautner said the discounts on the sentences `` seems to be like shopping at Costco . '' Lohan likely qualifies to serve her sentence in home confinement , instead of a jail cell , but the probation officials will decide that , Whitmore said . A report prepared by Lohan 's probation officer and released Wednesday said , `` It would appear that the defendant 's criminal conduct is increasing in seriousness and severity , '' yet it suggested she serve her sentence on probation and not in jail . Despite several months in court-ordered drug rehab last year , Lohan `` appears to be continuing to struggle with substance abuse issues . '' She tested positive for alcohol use , a violation of probation rules , in February , the report said . It also revealed that the drug test failure last August , which resulted in a jail sentence and court-ordered rehab , involved cocaine and amphetamines . Sautner ordered that Lohan remain on supervised probation until she completes 480 hours of community service included in her punishment . But the judge rejected Deputy City Attorney Melanie Chavira 's request for substance abuse counseling for Lohan . Sautner said drugs and alcohol are not the root of Lohan 's legal troubles , but `` she 's got other problems for which she self-medicates . '' Lohan 's four years in and out of court -- and sometimes jail -- started with two drunken driving arrests in 2007 . Since then , she 's spent more than eight months in substance abuse rehab . Lohan is already two days into completing her 480 hours of community service , including 360 hours at the Los Angeles Downtown Women 's Center . `` I have already started my community service at the Downtown Women 's Center and thank everyone there for their warm welcome , '' Lohan said . `` I hope to be able to fulfill my obligation without any press attention . I think the media spotlight should be on issues such as homelessness and domestic violence instead of on me . '' Sautner said she 's asked Los Angeles police to keep the paparazzi away from the center while Lohan performs her service .
