Friends of the troubled actress Lindsay Lohan have said they are very concerned as to how she will cope with her cigarette addiction during the 90-day stay in jail she is facing.

Lohan was told by Judge Marsha Revel that she needed to serve the jail term after a string of violations of the terms of an earlier sentence following a drink-driving incident in 2007. She has been told she needs to surrender herself to the women-only jail on the 20^th July.

The prison has a strict no-smoking policy and adopts a zero-tolerance approach to those breaking the rule. However friends have told gossip site TMZ that Lohan smokes at least two packets of cigerettes a day and for years hasn’t gone a day without smoking.

The source described her habit as a ‘serious condition’ and said they were ‘honestly scared’ for the star.

Friends have reportedly been urging her to give up now, so she can get acclimatised to the prospect of three months without smoking.

While in a similar case of extreme addiction to nicotine, a medication like Champix, Lohan is reportedly struggling with a severe dependence on a variety of other prescription medications, so medication probably won’t be an option to help her cope with her nicotine cravings.

She has also been told to attend  a rehab program as part of her sentence – hopefully this will help her change her lifestyle and get healthy!

The American Food and Drugs Agency, which regulates drug use in the U.S, has decided that there needs to be a label change for the smoking-cessation medication Champix. The change in the wording of the label will reflect concerns that the treatment may be linked to depression.
