The term “medical marijuana” refers to the use of the whole, unprocessed marijuana plant and its pure extracts to treat a disease or improve a symptom. It must be sourced from a medicinal-grade cannabis plant that has been meticulously grown without the use of toxic pesticides and fertilizers.Marijuana’s incredible healing properties come from its high cannabidiol (CBD) content and critical levels of medical terpenes and flavonoids. It also contains some tetrahydrocannabinol (THC), the molecule that gives the psychoactive effect, which most recreational users are after. Through traditional plant breeding techniques and seed exchanges, growers have started producing cannabis plants that have higher levels of CBD and lower levels of THC for medical use
