Hemp, Sativa, and Indica are all subspecies of the cannabis plant.

Hemp is a strain of cannabis that is grown specifically for industrial use and contains low levels of THC, the psychoactive compound found in cannabis. It is used for a variety of industrial and commercial purposes such as clothing, paper, biofuels, and construction materials.

Sativa strains are known for their energizing and uplifting effects. They tend to have a high THC content and are often used to help with depression, fatigue, and lack of appetite. They are also used to enhance creativity and focus.

Indica strains are known for their relaxing and sedating effects. They have a high CBD content and are often used to help with anxiety, pain, and insomnia. They are also used to promote rest and relaxation.

It's important to note that most strains on the market are hybrids, which means they are a combination of both Sativa and Indica genetics, and can produce a wide range of effects depending on the specific genetics.
