Quick answer

Hemp THC products are items made from Cannabis sativa L. plants that test at 0.3 percent delta-9 THC or less by dry weight. The word hemp describes the plant, not the effect. Many of these products contain intoxicating cannabinoids such as delta-8 THC, delta-10 THC, THCP, or hemp-derived delta-9 THC. Federal law controls the plant. State law controls the finished product, and the rules differ by state.

Which cannabinoids count

  • Delta-8 THC. Made from CBD in a lab process. Intoxicating.
  • Hemp-derived delta-9 THC. Delta-9 pulled from hemp, then dosed into gummies, tinctures, or vapes.
  • Delta-10 THC. Intoxicating. Fewer products on the market.
  • THCP and THCV. THCP binds the CB1 receptor. Early lab work reports higher potency than delta-9 in some assays. Human data is thin.
  • HHC and THC-O. Made in a lab, not pulled from a plant. THC-O is a synthetic acetate.

Federal law and the 0.3 percent rule

The 2018 Farm Bill removed hemp from the Controlled Substances Act. It defines hemp as Cannabis sativa L. with a delta-9 THC concentration of 0.3 percent or less on a dry weight basis. Three parts of that rule matter.

  1. The threshold counts delta-9 THC. Delta-8 THC, THCP, and other intoxicating cannabinoids sit outside the number.
  2. The measure is dry weight of the plant or the product, not per serving.
  3. There is no federal cap per package.

That math creates room. A 100 gram gummy at 0.3 percent delta-9 THC can hold 300 mg of delta-9 THC and still meet the letter of the law. A single 10 mg dose compares to 300 mg in the same package.

THC From Hemp: What It Is and How to Read a Label

Congress has not passed a federal ban. A 2024 House farm bill draft would have banned most hemp-derived intoxicating cannabinoids. The amendment was withdrawn during committee markup.

How to Buy Hemp-Derived THC: A Comprehensive Buying Guide

State law

States set their own rules for intoxicating hemp products. Common approaches include a ban on delta-8 THC, a cap per serving, a cap per package, a purchase age of 21, and testing or labeling requirements. Some states treat hemp THC like cannabis and route sales through licensed dispensaries. Check the rules in your state before you buy.

Dose and timing

Packages vary. Delta-8 gummies sold online run from 10 mg to 50 mg per piece. Hemp delta-9 gummies in states with caps often run 5 mg to 10 mg per piece.

Edibles take 30 to 90 minutes to hit. Peak effects land at 2 to 4 hours. Effects last 4 to 8 hours. Start at 2.5 mg to 5 mg. Wait 2 hours before taking more. Vaped or smoked hemp THC hits in minutes and clears in 1 to 3 hours.

What a lab report should show

  • Cannabinoid panel with delta-9 THC, delta-8 THC, and total THC.
  • Pesticides, heavy metals, residual solvents, mycotoxins, and microbials.
  • A batch number that matches the package.
  • A lab name and ISO 17025 accreditation.

Peer-reviewed testing of delta-8 products has found listed amounts that differ from measured amounts. Ask for the certificate of analysis for your batch.

Drug tests

Standard urine screens look for 11-nor-9-carboxy-THC, a metabolite of delta-9 THC. Delta-8 THC breaks down into a close metabolite and can trigger the same result. One use can produce a positive. CBD isolate products carry lower risk, but no hemp product is risk free.

Federal agency position

The FDA has not approved any hemp-derived THC product for any use. The agency has issued warning letters over delta-8 THC products sold as dietary supplements and over marketing claims. FDA states that delta-8 THC products cannot be sold as dietary supplements.

Before you buy

  1. Read the total THC per package, not per gummy.
  2. Match the batch number on the package to the COA.
  3. Check delta-8 and delta-9 content as separate numbers.
  4. Confirm the seller checks age and ships to your state.
