Hemp vs. Cannabis

Hemp and cannabis are fundamentally different plants that happen to originate from the same Cannabis Sativa herb species. They serve different purposes, and they vary entirely in function, cultivation, and application. For example, the hemp plant does not possess psychoactive substances, while the marijuana plant does. That’s because hemp has low levels of THC (< 0.3%), while marijuana has high levels of THC (5%-35%). It would be practically impossible for you to get high by consuming hemp.

Marijuana is used for medicinal and recreational purposes, while hemp is used in the automotive industry, body care, clothing, construction, food, plastic, and other fields. Their chemical makeup is also completely different, other than the levels of THC in the plants; hemp is rich in CBD, which acts as THC antagonist.

Growing hemp is relatively easy. You can cultivate it in large fields, close together and it requires minimal care. It’s even adaptable in most climates. Marijuana, on the other hand, needs special requirements, like a carefully controlled atmosphere, which is warm and moist, and it also requires extra care.
