What Is Delta 9 THC? Hemp-Derived Delta 9 Explained

Posted by Bill Brink on Jul 20th 2022

What Is Hemp Derived Delta-9 THC & Is It Legal?

Delta 9 THC is the main compound in cannabis that causes a high. When people say “THC,” they almost always mean Delta 9. Hemp-derived Delta 9 is the exact same molecule, extracted from hemp plants instead of marijuana. So what is Delta 9 like, how is hemp-derived Delta 9 different, and how should you take it? Here is a plain-English guide.

What is Delta 9 THC?

Delta 9 tetrahydrocannabinol is one of more than 100 cannabinoids found in the cannabis plant, and the most abundant intoxicating one. Its name comes from its structure: a double bond on the ninth carbon atom of its carbon chain. Delta 9 binds to CB1 receptors in your brain and nervous system, which produces the effects most people associate with cannabis: euphoria, relaxation, a shift in how you perceive time and sound, and often an appetite boost.

Hemp-derived Delta 9 vs marijuana Delta 9

Chemically, there is no difference. Delta 9 from hemp and Delta 9 from marijuana are the same molecule and affect your body the same way. The differences come down to the plant and the rules:

  • Source plant: hemp and marijuana are both cannabis. Hemp has been legally defined by its low Delta 9 THC content, traditionally no more than 0.3% by dry weight.
  • How products are made: hemp-derived Delta 9 is extracted from hemp, then measured into products like vapes, infused flower and gummies.
  • Where it is sold: hemp products have been sold online and in shops, while marijuana is sold through state-licensed dispensaries.

Delta 9 vs THC: are they the same?

Yes. “THC” is shorthand for Delta 9 THC. Other forms of THC exist, and it helps to know how they relate:

  • THCA is the raw acid form that turns into Delta 9 when heated. See THCA vs THC.
  • Delta 8 is a milder isomer. See Delta 8 vs Delta 9.
  • Delta 10 is a lighter isomer often described as energizing.

Does Delta 9 get you high?

Yes. Delta 9 is the compound responsible for the cannabis high, and hemp-derived Delta 9 produces the same effects milligram for milligram. How strong it feels depends on the amount, the format and your tolerance.

How long does Delta 9 last?

Format Kicks in Typically lasts
Disposable vapes and carts 1 to 10 minutes 2 to 4 hours
Pre-rolls and moonrocks 1 to 10 minutes 2 to 4 hours
Wax and dabs Within minutes 2 to 4 hours
Tinctures (held under the tongue) 15 to 45 minutes 4 to 6 hours
Gummies and edibles 30 to 120 minutes 4 to 8 hours

How much Delta 9 should you take?

  • Vapes and smokables: take one or two puffs and wait 10 to 15 minutes before taking more.
  • Edibles and tinctures: start with 2.5 to 5mg and wait at least two hours before taking more.
  • Experienced users can build up slowly from there. More is not always better, and too much can feel uncomfortable.

Does Delta 9 show up on a drug test?

Yes. Hemp-derived Delta 9 is the same THC that drug tests are designed to detect. Detection windows depend on how often you use THC, your metabolism and the type of test. A few days is common for occasional users, while frequent users can test positive for several weeks. If you are drug tested, avoid Delta 9 products.

Is hemp-derived Delta 9 legal?

Since the 2018 Farm Bill, hemp products have been allowed federally when they contain no more than 0.3% Delta 9 THC by dry weight. Congress has since changed the federal definition of hemp, and many states set their own rules, so the answer depends on where you live. Check your state’s current laws before ordering.
