One of the most popular topics in cannabis is Delta-8 THC. It is a minor cannabinoid that can get you high as traditional THC but in a much lower amount. Delta-8 is found in very small quantities in cannabis plants and is often converted to CBD. It is a compound that you will likely soon learn if you don't know about it.
The #1 reason why delta-8 products are so popular is that they can be made from hemp. The 2018 farm bill has made cannabis with less than 0.3% THC legal. Anything that is naturally derived from hemp is now federally legal. In many states, it is available for sale federally. You can buy delta 8 THC via https://d8.co/pages/what-is-delta-8-thc.
This means that if you convert hemp CBD to delta-8, you will end up with a federally legal cannabis product that can get people high but less than traditional THC. Some states have started to regulate delta-8.
The second reason people are so interested in delta-8 is that it is supposed to be much less intense and much more approachable than traditional cannabis with THC. Experience with cannabis, frequency of use, and your body chemistry all come into play when deciding how high one will get. Consumption results may vary.
