👉 Hemp is a type of cannabis plant that grows in certain regions, such as North America, where it has been cultivated for centuries. Hemp is often referred to as the "cannabis seed" because it contains the genetic material necessary for growing plants with THC (tetrahydrocannabinol), which is one of the psychoactive chemicals found in marijuana. The plant's high THC content makes hemp a popular alternative to marijuana, particularly among people seeking legal medical cannabis use in some countries.
