Hemp and marijuana are both Cannabis sativa L. — the same plant species. The only legal distinction is Delta-9 THC content: hemp is legally defined under the 2018 Farm Bill as cannabis containing 0.3% or less Delta-9 THC by dry weight. Marijuana is cannabis above 0.3% Delta-9 THC and remains federally Schedule I. This single percentage point defines the entire difference in federal law, allowing hemp-derived cannabinoids — CBD, Delta-8, Delta-9 in trace amounts, THCA, THCP, and others — to be legally grown, sold, and shipped, while traditional marijuana products remain restricted to state-legal dispensaries.

What is the biological difference between hemp and marijuana?

Biologically, there is no separate cannabis species called “hemp” or “marijuana” — these are legal and cultural terms applied to Cannabis sativa L. plants based on their cannabinoid content. High-THC cannabis (marijuana) has been selectively bred over decades for high Delta-9 THC concentrations (15–30%+). Industrial hemp was bred for fiber and seed production with incidentally low THC. Today’s hemp THCA flower is a modern category — cannabis genetics bred to maximize THCA content while keeping Delta-9 THC under 0.3%. The plant looks, smells, and when smoked, produces the same effects as traditional marijuana — because THCA converts to Delta-9 upon heating.

How does the 0.3% THC rule work in practice?

The 0.3% Delta-9 THC threshold applies to dry weight of the whole plant or product. For THCA flower, testing is conducted on the raw (unheated) plant material — which shows near-zero Delta-9 THC even if THCA levels are 25%+. For hemp edibles, the 0.3% threshold applies per serving, meaning a large gummy (3.5g) can legally contain 10.5mg of Delta-9 THC (0.3% of 3,500mg). This calculation is how legal hemp gummies with 10–50mg Delta-9 THC are sold online and in stores. The FDA is aware of this framework and has expressed concerns but has not enacted new restrictions as of 2026.

What can you legally buy online that you can’t get in a dispensary?

Hemp-derived products available online include: THCA flower (functionally equivalent to dispensary cannabis when smoked), Delta-9 gummies with 10–50mg per piece, THCP products (not typically found in dispensaries), Delta-8 products (varies by state), THCA diamonds (high-purity concentrates), and novel cannabinoid blends. Traditional dispensaries primarily sell marijuana products with well-characterized THC percentages but face higher taxes (cannabis excise tax of 15–37% in most legal states), age verification requirements, and limited cross-state availability. Hemp online products are often lower-priced due to absence of cannabis-specific taxes.
