Harlequin strain

The Harlequin strain is one of the best-known CBD-dominant cultivars, valued for delivering relaxation without much intoxication. Leafly says it lets people unwind while staying clear-headed and unsedated. Is Harlequin indica or sativa? It is a sativa-leaning hybrid of Colombian Gold, Thai and Swiss sativas with a Nepali indica; AllBud and CannaConnection list about 75% sativa.

Its cannabinoid ratio is the main reason people seek it out. Leafly's lab-data medians are 9% CBD and 5% THC, CannaConnection cites up to 15% CBD with THC around 4–7%, and many sellers describe it as roughly 5:2 CBD to THC. That means it is not THC-free: most people notice a mild shift in mood, but far less intoxication than from a typical THC strain. Aroma-wise, Leafly reviewers call it woody and earthy with herbal and floral notes, Leafly describes flavors from earthy musk to sweet mango, and AllBud adds citrus. The lab data shows myrcene first and pinene second, a pairing that gives it a fresh, green, slightly fruity smell.

Harlequin effects in Leafly's user data are led by focused and relaxed, followed by uplifted and happy, with little of the euphoria or sleepiness seen in THC-dominant strains. Consumers most often mention physical discomfort such as soreness, aches, muscle tension and headaches, as well as fatigue. Side effects are rarely reported in Leafly's data; none of the usual complaints scores high, and anxiety and paranoia sit far below the levels seen for THC-heavy sativas.

Compared with ACDC and Charlotte's Web, Harlequin carries noticeably more THC, which some consumers prefer for a mild lift; compared with Cannatonic, it is more consistently CBD-dominant than that strain's mixed seed chemotypes. Leafly rates it easy to grow and tall. For anyone growing it for its ratio, lab testing is the only way to confirm what a particular harvest contains.

Harlequin's history is thinly documented. Accounts in strain guides credit a breeder known as Mr. Green of the House of David Collective in Northern California with crossing Colombian Gold, Thai and Swiss landrace sativas with a Nepali indica in the mid-2000s, reportedly while aiming for a hash plant. Its unusual CBD-rich chemotype came to wider attention as lab testing spread in the late 2000s and early 2010s. Leafly and CannaConnection agree on the landrace lineage, but the breeder story has not been confirmed by a primary source.
