lindsay lohan drug test Lindsay Lohan uses Twitter to admit failed drug testLindsay Lohan has come clean about not staying clean.

The actress has taken to Twitter to admit that she failed a drug test, which could potentially send her back to jail for 30 days. One of the conditions Judge Elden Fox imposed on her earlier this summer, following her jail stint and rehab, was that she submit to random drug tests.

TMZ reported on Friday (Sept. 17) that Lohan had failed a couple drug tests. Lohan at first denied it, but late Friday she tweeted that she had indeed tested positive for drugs.

“Regrettably, I did in fact fail my most recent drug test and if I am asked, I am prepared to appear before Judge Fox next week as a result,” she writes. “Substance abuse is a disease, which unfortunately doesn’t go away over night. I am working hard to overcome it and am taking positive steps forward every day. I am testing every single day and doing what I must do to prevent any mishaps in the future.”

I am keeping my faith, and I am hopeful." Lohan was sentenced to jail and rehab in July for violating probation on an earlier DUI charge. She served about two weeks of a 90-day jail sentence — which is not uncommon for nonviolent offenders — and then left inpatient rehab at UCLA Medical Center after just three weeks in favor of outpatient therapy. It apparently didn’t work out all that well. She hasn’t been told to appear in court yet, but if she does it could mean a return trip to the pokey.
