If you’ve shopped hemp products for more than five minutes, you’ve probably seen both delta-8 and delta-9 on labels, likely without a clear explanation of what separates them. They sound like variations on the same theme. They’re not — and the difference actually matters for what you’re putting in your body and where it came from.
They’re both THC — just not the same molecule. Delta-9 THC is the cannabinoid most people mean when they say “THC” — it’s the primary compound found naturally in the cannabis plant, hemp included, and it’s what’s been studied the longest. Delta-8 THC is a related but distinct cannabinoid, occurring only in trace amounts naturally. Because there’s so little of it in the plant itself, nearly all delta-8 on the market today is chemically converted from CBD in a lab, not naturally extracted.
