As “Teen Mom OG” star Catelynn Lowell struggles with depression and anxiety, the reality star offended some fans when she drove under the influence of marijuana on Monday’s episode. The mother-of-one took to Instagram to defend herself after viewers slammed her on social media.

Catelynn posted a picture of a quote from reggae legend Bob Marley and captioned it with the OK hand and lips emoji. “Who are you to judge the life I live? I know I’m not perfect and I don’t live to be, but before you start pointing fingers make sure your hands are clean,” the MTV reality star wrote. The post was liked more than 33,500 times by her 2.3 million followers by Wednesday morning.

Though Catelynn didn’t talk about using weed specifically on Twitter, she wrote she was sorry for “medicating” herself. She added she didn’t like to take Xanax, which is a prescription drug used to help alleviate anxiety.

“Yes, I was 100-percent wrong for medicating while driving. That was before I got my card and I know better now. Indica [sic] species=less anxiety #NoXanax,” the Michigan native wrote Tuesday. “What works for me may not work for you, but I didn't like how Xanax made me feel. I like the organic route.”

When she was praised by some fans for her apology, Catelynn added: “I always admit when I screw up, I'm a human being and deserve all the respect AND criticism that comes along with it.”

During the episode that aired Monday, one scene shows her husband, Tyler Baltierra, asking her on the phone: “Where’s the roaches at?” “Roach” is a slang term for the remnants of a joint.

After that, Catelynn puts her sweater over the MTV camera. A lighter is heard in the background, along with Catelynn coughing. “We’re going to boogie town,” her mother, April, says. Then the two get in the car and drive.

Though it seems obvious they were smoking weed, Tyler confirmed it in his own tweets, claiming marijuana is legal in Michigan. 

“Weed is definitely legal in MI,” he tweeted Monday. “I should know, because I don’t break the law… I follow it respectfully.”

Marijuana is actually only legal in Michigan if someone has a debilitating medical condition. It’s always illegal to drive under the influence.

MTV hasn’t responded to the criticism.
