Although many people think there is no difference between the terms “marijuana” and “cannabis”, their meaning is not quite the same. Cannabis is usually taken as a short name for products derived from the most popular version of the cannabis plant, called Cannabis Sativa. Hemp, also known as industrial hemp is a variety of this plant with a high concentration of CBD cannabidiol, which has no psychoactive characteristics. Marijuana is a word, usually used when talking about parts of the plant or products with a high concentration of THC. Significant presents of this compound can have serious effects on the mental state of the consumers.
