Lindsay Lohan’s Plea Deal — One String Attached … I WANT MY ADDERALL

Exclusive 0331_lindsay_lohan_adderall_composite2Lindsay Lohan drew a line in the sand during plea negotiations in her lying-to-cops case — she”d agree to rehab ONLY if the facility would allow her to continue taking Adderall … sources close to LiLo tell our sources.

Our sources say Lindsay has taken Adderall — used to treat Attention-deficit/hyperactivity disorder and misused for various other purposes — daily for years.  She believes she needs it to function.

We”re told Lindsay was steadfast — either attach Adderall to the deal or she”d take her chances at trial.  Sources say Lindsay”s lawyer, Mark Heller, assured her he could find a lockdown rehab facility that would accommodate her demand.

Heller may not be able to deliver … fact is, there”s no such thing as a lockdown rehab facility that would take Lindsay, much less allow her to take the drug.

It”s pretty ironic … when Lindsay was jailed back in 2010, she got a doctor to prescribe Adderall while she was behind bars … even though her ADHD diagnosis was called into serious question.

A number of people in Lindsay”s life believe it was the Adderall that led to her downfall.
