Amnesia Haze is a sativa-dominant cultivar that combines Jamaican, Laotian, Hawaiian, and Afghani genetics into a complex and potent Haze variety. With a notably long flowering time of 70-80 days, Amnesia Haze demands patience from cultivators but rewards them with a strain that has become a European favorite and a global benchmark for quality sativa effects. Its citrus-earthy-sweet aroma, combined with intensely uplifting and creative cerebral effects, has made it one of the most respected Haze-dominant strains in the cannabis world.

Amnesia Haze is a multi-origin cross:
Parent lineage: Jamaican x (Laotian x Hawaiian) x Afghani
The strain was developed in the Netherlands and gained particular popularity across Europe, where it became a staple of coffee shops and dispensary menus. The complex multi-landrace genetics produce a strain with a uniquely layered terpene profile and potent sativa effects. Amnesia Haze has been widely cloned and pheno-hunted, and several phenotype selections (including Amnesia Haze Original, Amnesia Haze x Lost Farmer, and others) exist across different seed banks.
| Cannabinoid | Typical Range |
|---|---|
| THC (Total) | 20-25% |
| CBD | <1% (typically 0.1-0.3%) |
| CBG | 0.5-1.5% |
| CBN | <0.5% (increases with age) |
Amnesia Haze occupies the high THC range, making it one of the more potent sativa strains commonly available. The high THC content, combined with its clear-headed sativa effects, makes it suitable for experienced users.
| Terpene | Approximate Share | Notes |
|---|---|---|
| Terpinolene | 25-40% | Primary terpene; floral, herbal, citrus associated with energizing, creative effects |
| Caryophyllene | 15-25% | Spicy, peppery depth adding earthiness |
| Myrcene | 10-15% | Present in higher amounts than many sativas, adding earthy body to the profile |
| Pinene | 5-10% | Subtle pine freshness |
| Limonene | 3-8% | Citrus notes enhancing the overall bright character |
The terpinolene-caryophyllene-myrcene combination produces the citrus-earthy-sweet aroma that defines Amnesia Haze.

Amnesia Haze is a challenging strain to grow. The very long flowering time (70-80 days) demands patience and consistent environmental management. The significant sativa stretch requires aggressive training and height control indoors. The multi-landrace genetics produce a vigorous but demanding plant that rewards experienced growers with substantial yields. Outdoor harvest in the Northern Hemisphere typically falls in late October to early November, and the plant can grow very large. The extended flowering window means growers must be vigilant about mold and bud rot as the season progresses.
