Hemp and cannabis are two varieties of the same plant species, Cannabis sativa. However, they differ in their chemical composition, cultivation, and usage.
Hemp is typically grown for industrial use and contains very low levels of THC (tetrahydrocannabinol), the psychoactive compound that produces the "high" associated with cannabis use. In fact, in most countries, hemp is legally defined as cannabis with less than 0.3% THC content. Hemp is used for making a wide variety of products, including textiles, paper, building materials, fuel, and food products such as hemp seeds and hemp oil.
On the other hand, cannabis is typically grown for its high THC content and is used for recreational or medicinal purposes. It contains higher levels of THC than hemp and has a range of other compounds, including CBD (cannabidiol), which has been shown to have various therapeutic properties.
In summary, hemp and cannabis are different varieties of the same plant species, but they differ in their chemical composition, cultivation, and usage. Hemp is grown for industrial purposes and has low levels of THC, while cannabis is grown for recreational or medicinal purposes and contains higher levels of THC and other compounds.
