Lindsay Lohan Time is Not on Her Side

7/7/2010 10:00 AM PDT BY TMZ STAFF
Friends of Lindsay Lohan tell TMZ ... they fear for her safety -- even her survival -- during her two weeks of freedom before going to jail.

The judge could have sent Lindsay to the slammer immediately, but instead gave her until July 20 to turn herself in.  Friends worry that Lindsay is now fully off the hinges and may not be able to resist the drugs and alcohol.

The catch-22 -- if Lindsay falls off the wagon she could end up getting even more jail time.  Even worse, her friends worry Lindsay could become so irrational she could harm herself.

As if there weren't enough temptation ... there's a big belated birthday bash for Lindsay set for tonight at an L.A. club -- not the best place for a future inmate with a SCRAM accessory
