There are no legal age restrictions specified by federal legislation. Delta 8 THC flower is categorized like a legal hemp plant, and federal law makes no restrictions on who may get legal hemp products based on age or other factors. Instead, each state determines the age requirement for purchasing Delta 8 thc flower.
There are relatively few conditions defined at the state and local level that particularly impact the age requirement for purchasing Delta-8 hemp flower.
Many jurisdictions let people buy hemp-derived CBD products just at age of eighteen, but certain states may have restrictions that make obtaining Delta-8-THC much more difficult. Some states don't distinguish between CBD and Delta-8, lumping them both together as "hemp products."
Many Delta-8 brands or distributors restrict buyers to 21 years old to obtain Delta-8 items due to differences in state legislation. This corresponds to the minimum age for purchasing Delta-9-THC goods in jurisdictions where recreational marijuana is allowed.
In other words, the age restriction for purchasing Delta-8-THC isn't necessarily set by state or federal legislation. Instead, many Delta-8 distributors established a 21-year-old age limit.
