The 2018 Farm Bill as it is commonly known, or more formally H.R. 2: The Agricultural Improvement Act of 2018, made Delta-8 federally legal. It allows for all isomers, cannabinoids, and derivatives from Hemp that are not Delta-9 THC to be considered legal.
While Delta-8 is federally legal and legal is most states and areas, it is not legal in all states. It is important that you are aware and abide by all state and local laws regarding Hemp and Delta-8 products.
