I added a new paragraph to better explain the answer to your question. 

> Delta-10 is still a fuzzy topic, there is not a ton of info about it yet. So far we know that it is a cannabinoid that interacts with the CB1 receptor, causing psychoactive affects. Delta-10 bonds to the tenth carbon chain, which is what mainly differentiates it from Delta-9 and 8.

Basically it's pretty much the same as Delta-9, except it has a slightly different structure which allows it to be classified as federally legal, thanks to the 2018 Farm Bill. This is similar to the case for Delta-8, except there still needs to be more studies that determine the precise differences between Delta-10, 9, and 8.
