C3PO is a high-CBD hybrid cannabis strain of undocumented lineage, known for a fresh pine and lemon aroma and very low THC. Leafly says it is grown by Petrolia Farms in Humboldt County, California. Both Leafly and AllBud put CBD around 13% to 15% with THC at or below 1%, so users describe calm and clarity rather than a strong high.

Where C3PO Comes From
C3PO is named after the fussy protocol droid from Star Wars. Leafly describes it as a Humboldt County, California strain cultivated by Petrolia Farms, while AllBud says its origins are unknown and that it is thought to be a cut of OG Kush. Neither source documents a breeder or a confirmed cross, so the OG Kush link is speculation.
What both sources agree on is the chemistry. C3PO is a CBD-dominant strain, with CBD usually in the 13% to 15% range and THC under about 1%. That ratio sets it apart from most strains named on dispensary menus and puts it in the same category as other high-CBD varieties.
The two databases disagree on how it leans: Leafly calls it sativa-dominant and AllBud lists it as about 60% indica. With a ratio like this, the indica or sativa label tells you less than the CBD number does.
C3PO Effects: What It Feels Like
Because THC is so low, C3PO does not produce the strong euphoria of a typical strain. Leafly describes relaxing effects with mental clarity, and its reviewers most often report relaxed, focused, energetic, hungry and creative. AllBud describes a light, uplifting boost in mood followed by a settling calm in the body, and lists euphoria, mellow, relaxing and uplifting.
That makes it a reasonable choice for daytime use, for people who want to stay clear-headed, or for those who are sensitive to THC. Effects still vary from person to person, and some reviewers report mild sleepiness.
C3PO Terpenes, Aroma and Flavor
Pine is the consistent note. Leafly describes the smell of fresh pine, and its reviewers tag cheese, pine, diesel, lemon and earth. AllBud describes sweet earthy citrus and pine with a touch of herbs on the exhale, and compares the aroma to a mellow pine cleaner with lemon and sweet spice.
Neither source publishes a terpene profile for C3PO.
Side Effects and How to Use C3PO
Leafly reviewers mention dry mouth most often and dry eyes occasionally. With THC this low, anxiety and paranoia rarely come up, though CBD can make some people a little drowsy.
With C3PO, as with any strain, a smaller dose usually avoids anxiety or grogginess. Our cannabis safety guide covers what to do if you take too much.
Do People Use C3PO for Medical Reasons?
Leafly reviewers most often mention anxiety, stress, inflammation, insomnia, pain and depression. AllBud reviewers mention chronic pain, inflammation, neuropathy and, in one case, multiple sclerosis pain. These are personal reports, not clinical evidence, and anyone with a medical condition should talk with a clinician.
