In my early twenties, I had everything in the palm of my hand. I was a journalist, published author, and was passionate about cannabis. Quickly realizing that the cannabis industry wasn't going to take off the way I wanted it to, I decided I needed a change.After some soul searching and self-reflection, I realized that all of my passions were centered on wellness. CBD is an incredible healing tool with scientific research backing its effectiveness in alleviating anxiety and promoting restorative sleep. With CBD becoming a more mainstream topic every day (not just among the medical community), it seemed like this was something that could be well worth pursuing!
