ACDC: Cultivar Profile With Sources, Lineage Claims and Lab Data Limits

Quick answer

ACDC is a cultivar name (commonly called a strain) that sources describe as CBD-dominant with little THC, and as descended from Cannatonic. Unlike most named cultivars, it has a documented chemical category in a peer-reviewed genetics study, but we found no verified batch values. Evidence labels used here: marketing claim means a seller or media statement with no study behind it, and insufficient evidence means too little reliable research to judge. This page is information only, not medical or legal advice.

Identity and names

The name is said to stand for "Alternative Cannabinoid Dietary Cannabis," according to the original breeder, as reported by a cannabis media site.[1]

Reported lineage and breeder claims

• Breeder attribution (reported). The media site names Dr. William Courtney, a Northern California physician, as creator of the chemovar, using Cannatonic seeds he bought in Barcelona from the Spanish seed company Resin Seeds, according to a magazine account.[1]
• Parentage (reported). One encyclopedia says ACDC is made from a phenotype of Cannatonic.[2] The media site adds that some online seed banks describe it as Cannatonic crossed with ruderalis, a wild-type cannabis.[1]
• Parent cultivar variation. The media site says that, according to Cannatonic's breeders, as many as a quarter of Cannatonic plants can produce high levels of THC, while ACDC plants do not produce more than a small amount.[1] That is a breeder statement, not a measurement.
• Genetic evidence. A 2025 genetics paper sequenced one fresh ACDC sample but did not test the lineage story.[3]

Confidence: moderate for Cannatonic as the source, reported for the breeder and the physician's role.

Classification

The encyclopedia calls it a hybrid,[2] and the media site says it is widely listed as a 50-50 indica and sativa hybrid, while noting that predicting effects from indica or sativa origins has little science behind it.[1] The more useful category is cannabinoid dominance. A 2025 Canadian genetics paper calls ACDC a Type III cultivar known for high CBD and low THC, and the category came from a licensed producer's data for the fresh sample.[3] The encyclopedia likewise calls it CBD-dominant.[2] See THC-dominant, CBD-dominant and mixed chemotypes.

Aroma

Reported flavors are woody, earthy and pine,[2] with myrcene, pinene and caryophyllene named as terpenes. The media site lists herbal, woody, spicy and citrus notes.[1] These are descriptions without batch details.

Potency

Verified batch data was not available. Both web sources show CBD and THC figures, but they are headline or averaged numbers without a batch, laboratory, test date or method, so we do not repeat them. The Canadian genetics paper classifies the cultivar but does not publish cannabinoid values for the sample in the text we read.[3] Composition varies by producer and batch, and a CBD-dominant name does not guarantee a low-THC result.

Reported experiences (anecdote)

A marketplace summary of reader reports lists relaxed, focused and uplifted as top effects.[2] The encyclopedia text also says the cultivar produces little to no intoxicating effects.[2] These are self-reports and seller descriptions, not controlled research.

Research

Proper evidence not found for clinical research on ACDC flower. We searched Europe PMC for the name: it appears in a genetics paper where it is one of many sequenced cultivars.[3] The encyclopedia says patients choose it for pain, anxiety, epilepsy and chemotherapy effects;[2] this is a marketing claim, and the evidence for those uses is insufficient evidence for this cultivar. Studies of purified CBD or approved medicines cannot be transferred to flower. See CBD, approved cannabinoid medicines and Cannabidiol and epilepsy.

Safety

Low THC does not mean no effects or no interactions. CBD can interact with other medicines; see CBD-medication interactions and talk with a prescriber before combining products with prescriptions. Composition varies by batch, so check the label, and cannabis in general can impair thinking, memory and body movement.[4] In the US, call 911 in an emergency or Poison Help at 1-800-222-1222.
