Lindsay Lohan Claims Tea Made Her Fail Alcohol Test

Lohan has been telling friends she's been drinking her favorite kombucha tea again ... the same tea that caused her probation officer to raise a red flag earlier this year because it contains alcohol. The company behind the drink claims the alcohol content is less than .05%.

Of course, the judge ruled that Lindsay is ALLOWED to consume alcohol during her house arrest sentence ... so the dirty test didn't matter anyway.

TMZ spoke with Lindsay about the situation ... and she told us, "I am responsible, and I'm following the rules and obeying my judge and the Los Angeles judicial system."
