Primitiv is a cannabis research company dedicated to compassionately serving medical marijuana patients throughout the United States, including our home state of Michigan. Founded by Calvin Johnson, Jr. and Rob Sims, former NFL teammates who suffered from the long-term physical effects of injuries sustained during their playing careers, Primitiv seeks to advance the cause of medicinal cannabis by researching the natural health benefits of the plant. In a physically demanding sport like professional football, players learn to deal with the pain. Often, they are prescribed opioid painkillers for treatment, which can lead to dependency and addiction. Johnson and Sims felt the need for a more holistic approach to their pain management, and thus Primitiv was born.
