- Please note: they are now able to extract a certain compound from the cannabis plant that provides medicinal benefits and relief, but without the psychoactive ingredients that normally produce the 'high' when the plant is ingested whole. The extracted compound is called CBD (cannabidiol). Although it's said that the therapeutic benefits are more effective when the plant is consumed in it's natural (whole) form as there are many different cannabinoids/compounds that make up the chemistry of the plant and are said to have a synergistic effect when ingested in the human body. There are also strains available that have lower concentrations of THC (psychoactive) and higher concentrations of CDB (non-psychoactive).
