Cannabis oil refers to the beneficial, sometimes psychoactive oil rendered and extracted from any plant in the Cannabis family. Currently under the blanket description of Cannabis Oil, we have 2 main descriptors used to differentiate between types of Cannabis oil.
If the Cannabis plant that the oil is rendered from has more than .3% THC by dry weight, it is considered to be a marijuana plant by most nations, and the oil produced from such a plant would rightfully be described as either Cannabis Oil, Hash Oil or Marijuana Oil.
