CBD can be extracted from both marijuana and hemp, making both plants useful. The main difference between them is that marijuana contains a high level of THC and a low amount of CBD, while hemp contains a large level of CBD and a low amount of THC. Because of this simple fact, scientists are suggesting that CBD may potentially lead us to a better lifestyle.
Growing marijuana is a much more tedious task because you must maintain a proper schedule of lighting, watering, and trimming to maximize its overall quality. Meanwhile, hemp requires minimal care because of its ability to adapt to almost any climate. CBD is extracted from the seeds and stalks of the hemp plant while CBD is extracted from the flowers of marijuana. Moreover, industrial hemp is legal at the federal level whereas marijuana is not.
All in all, marijuana and hemp are similar because they originate from the same mother species, however, they differ in functionality, appearance, and cultivation.
