Kardashian said last year: "I started taking CBD and it really changed things for me. It calms me down automatically."
Recreational marijuana is legal in the state of California, where the Kardashian-Jenner family live.
Jenner likely uses marijuana to help her relax due to her hectic lifestyle, but she'll have one less job to do in 2021 as her family's reality show, Keeping Up with the Kardashians is coming to an end.
The E! reality series will air its final season next year, after 20 seasons and 14 years on television screens.
The family said in a statement when the news was announced last week: "It is with heavy hearts that we've made the difficult decision as a family to say goodbye to 'Keeping Up with the Kardashians'.
"After what will be 14 years, 20 seasons, hundreds of episodes and numerous spin-off shows, we are beyond grateful to all of you who've watched us for all of these years - through the good times, the bad times, the happiness, the tears, and the many relationships and children. We'll forever cherish the wonderful memories and countless people we've met along the way."
