Hemp vs marijuana

Two legal classifications of the same plant species (Cannabis sativa) — the federal definition draws the line at 0.3% delta-9-THC by dry weight.

Why it matters

Hemp and marijuana are not different species. They are both Cannabis sativa, classified differently by THC content for regulatory purposes. The 2018 Farm Bill defined hemp as cannabis with no more than 0.3% delta-9-THC; anything above that line remains federally Schedule I marijuana. Genetic cultivars selected for fibre or seed are inherently low-THC; cultivars selected for resin and flower are inherently higher-THC.

In practice

Practically, the distinction matters for legality, banking, taxation, and interstate commerce. The compounds themselves do not respect the line — CBD from hemp and CBD from marijuana are the same molecule, and “hemp-derived” THC products (Delta-8, Delta-9 in hemp, HHC) have generated a regulatory grey market.

Common confusion

“Hemp doesn’t have THC” is wrong. Hemp has limited THC by definition. The number is small but non-zero.
