Unfortunately, the truth came out when Jenelle ended up in jail earlier this week after failing a drug test.
Jenelle was sentenced to 48 hours in jail after she tested positive for marijuana when she was in court for other charges stemming from her April arrest.
Now that she's been released, Jenelle had to answer to her fans.
The reality star did not directly address the situation, but did retweet a RadarOnline article where an unnamed "source" (which could be Jenelle herself) says that she has kicked the heroin habit, but has been smoking pot lately because "a lot of things stress her out."
"She is trying so hard to do the right thing and is really making an effort to straighten out," they continue.
Surely, there are healthier, legal ways to deal with stress.
So, unless Jenelle wants to move to a state where medicinal marijuana is legal and can get a doctor to agree that pot would help the situation, it looks like she's just going to have to find another way to cope.
