"Teen Mom 2" viewers got to see Jenelle Evans fail her drug test on Tuesday night’s episode.

The young mother has been the most troubled of the “Teen Mom 2” group, and in the newest episode Evans had to choose between spending 45 days in jail for failing her drug test or have her probation extended for another nine months.

In the first episode of season 3 it seemed Jenelle Evans was trying to get on the right track now that she had finished rehab and broken up with her troubled boyfriend Kieffer Delp.

Evans failed to get rid of some friends who had a negative influence on her and eventually succumbed to peer pressure.

The star tried to drink a “detox shake” so she could pass her drug test, but it was to no avail.

Evans crawled into her car crying and called her mother to tell her that she was going to get “violated” after failing her test.

"She's violating me on Friday and I don't know if I'm going to jail or not!" 

The teen might have been confused by her parole officer telling her she was going to have to report her violation.  

Evans met with her lawyer a few days after and that’s when the “Teen Mom 2” star learned she had a choice between 45 days in jail or staying on probation for nine months.

Evans was diagnosed as bipolar while in rehab and she has chosen to treat her mental illness with marijuana.

Smoking the drug has been Evans’ only way to deal with her anxiety and she can’t imagine not being able to smoke for another nine months.

After talking with her mother at the park it seems Evans is going to choose 45 days of jail time rather than having to stay drug-free for nine more months.

The episode ends with the teen mom being hysterical in the car saying to herself, “I’m such a f*ck up.”
