CBD has become more and more popular in the last few years, especially as an alternative way to manage chronic illnesses and mental health. As CBD becomes more popular — and legal in most states for medical purposes — it’s no surprise that celebrities are now advocating for CBD acceptance.

CBD, also known as cannabidiol, is an active ingredient in marijuana and comes from cannabis plants. According to Dr. Michelle Ross, Ph.D., a neuroscientist and cannabis expert, CBD is non-psychoactive and may help with multiple health conditions. There isn’t much research on the benefits and risks of using CBD for your health, but people with physical medical struggles such as chronic pain and insomnia, as well as mental illnesses such as anxiety and depression, have found CBD helpful.

Though CBD is gaining attention for its use in medical settings, there’s still a ways to go before it’s widely accepted and research supports its health benefits. That’s why some celebrities are proponents of CBD usage for medical reasons. Many of them have dealt with chronic pain or anxiety. Others are advocates for CBD because their loved ones use it for their health. And there are a few who simply believed in the importance of CBD for a long time and helped in making it a more available option for those living with chronic conditions.

Here are 12 celebrities who advocate for the CBD community:
