Teen Mom OG's Catelynn Reveals When She First Started Smoking Weed

During this week's episode, the 25-year-old opened up about her 'young and crazy' past

Catelynn disclosed during a previous Teen Mom OG episode that she smokes marijuana -- but when did the 25-year-old first begin using cannabis?

"I started smoking weed when I was probably around 12 or 13, which I'm not proud of. But that was when I was young and crazy," the Michigan native -- who opted to get help for lingering mental health issues in this week's installment -- discloses in the video above.

Saying goodbye to her loved ones was understandably emotional -- but what was the hardest part of leaving her family for an extended period of time? Hear Catelynn open up about the experience in the clip -- and be sure to keep following her journey every Monday on TMOG at 9/8c (peep a sneak peek featuring Tyler from the next installment below).
