THC is only 1 of 50000 uses of cannabis hemp, correct?

Yes, that's correct. Cannabis hemp has been used for a variety of purposes throughout history, and it is estimated to have over 50,000 different uses. THC (tetrahydrocannabinol) is just one of the many compounds found in the cannabis plant, and it is the main psychoactive component that is responsible for the "high" associated with marijuana use. However, other compounds found in cannabis, such as CBD (cannabidiol), have also been studied for their potential health benefits, and hemp can be used for a wide range of industrial applications, including textiles, paper, biofuel, and building materials.
