Matthew Campbell has been working in the field of botany and agriculture for 20 years. Since he was a child he loved to spend his days in his grandfather's greenhouse and once he grew up he decided to dedicate his life completely to the study of plants. Shortly after graduating, he discovered that he was suffering from rheumatoid arthritis and, while searching for a cure, he became aware of the extraordinary beneficial effects that THC and CBD had on his body. His knowledge of cannabis and its properties led him to manage vast crops of this plant for medicinal purposes (and recently also for recreational ones) in Oregon, an activity to which he still dedicates most of his time.
