Amnesia emerged from the Dutch breeding renaissance that defined European cannabis in the late 1990s and early 2000s. Credited to Super Strains (formerly known in some circles as Hy-Pro Seeds), the original Amnesia rapidly became a coffeeshop staple in the Netherlands. Its sativa-leaning profile, racy energy, and unmistakable Haze-style bouquet set it apart from the heavier, Afghani-led indicas that dominated shelves at the time.
Within just a few seasons, Amnesia earned a reputation for potency and an uplifting, talkative high. By the mid-2000s, it was among the most requested sativas in Amsterdam, frequently listed simply as “Amnesia” on menus—sometimes alongside close relatives like Amnesia Haze. While Amnesia Haze later captured global headlines with high-profile cup wins, the original Amnesia retained its own loyal following, particularly among consumers seeking cerebral clarity and creativity.
The strain’s enduring popularity is tied to its consistency and market-ready traits. Growers across the EU favored Amnesia for its relatively strong yields and resin production, especially considering its sativa dominance. As modern labs proliferated, test data consistently confirmed the high-THC, low-CBD chemical profile that users had long reported.
In contemporary markets, Amnesia remains a measuring stick for sativa excellence and a foundational parent in numerous hybrids. Seedbanks and breeders have leveraged its distinct Haze-led character to produce variants like Amnesia Haze, Amnesia Lemon, and Amnesia x AK-47. Today, the Amnesia name signals a bright, energizing experience, reliably anchored by classic Haze terpenes and a potent cannabinoid punch.
Genetic Lineage and Relationship to the Haze Family
Super Strains’ Amnesia is widely understood to be a predominantly sativa hybrid rooted in the Haze family. Breeders have kept the exact recipe proprietary, but most accounts describe a Haze-dominant backbone complemented by old-world genetics. In European breeding, Haze hybrids often incorporate stabilizing influences from Skunk or Afghani lines, and many growers suspect a similar approach in Amnesia to tighten structure and improve flowering times.
In practice, the phenotype expression tracks to about 70–80% sativa characteristics. Internodal spacing, vigorous vertical growth, and a tendency toward soaring, clear-headed effects all support a Haze-first lineage. Compared with its cousin Amnesia Haze, the original Amnesia tends to flower slightly faster and may show a touch more structural discipline under indoor training.
It’s important to distinguish Amnesia from Amnesia Haze, which is a related but distinct cultivar. Amnesia Haze often skews further into tropical Haze components and can require extended bloom times of 10–12 weeks. Amnesia, by contrast, frequently finishes in the 9–10 week window when dialed in, a difference growers will feel in cycle planning and room turnover.
The broader “Amnesia” gene pool has also seeded a host of popular derivatives. Notables include Amnesia Lemon, which layers a pronounced citrus terpene emphasis, and crosses like Amnesia x AK-47 that add structure and resin density. These offshoots reinforce the importance of the original Amnesia as a breeding parent while preserving its signature uplifting vibe.
Macroscopic Appearance and Bud Structure
Amnesia presents elongated, tapering flower clusters with a classic sativa silhouette. Calyxes stack in tidy, foxtail-like arrangements when pushed under high-intensity light, producing a sleek, spear-shaped cola. The buds are typically lime to forest green, accented by abundant orange to deep tangerine pistils.
A mature Amnesia cola glistens with a heavy trichome coat, reflecting the strain’s reputation for potency. Many cuts show an above-average calyx-to-leaf ratio, which eases trimming and preserves bag appeal. Under magnification, expect crowded capitate-stalked heads and a high proportion of cloudy trichomes near peak ripeness.
Despite the sativa structure, flowers can feel deceptively dense when grown under optimized environmental control. Indoor growers often note that well-cured buds remain springy but compact, indicating balanced development and moisture migration. As with many Hazes, late-flower foxtailing can occur with excess heat or light intensity, but gentle training and canopy management keep structure cohesive.
The finished aesthetic hints at the sensory experience to come. A swirl of citrus, incense, and fresh herb may release even during trimming, signaling the terpinolene-led terpene stack. It’s a look and feel that many Haze devotees instantly recognize: crystalline tops, spicy-citrus aroma, and slender but substantial colas.
Aroma: From Incense to Citrus
Amnesia’s aroma is an archetype of the Haze family: bright, incense-like, and citrus-driven. The first impression often blends lemon zest with cedar shavings and a light floral lift. As the bud breaks, undertones of cardamom, sweet herbs, and a hint of peppery spice roll forward.
Terpinolene is frequently dominant, contributing a fresh, piney-citrus personality that reads “clean” and invigorating. Limonene layers in candied lemon and subtle grapefruit, while myrcene can round the profile with faint earth and softness. Secondary contributors like beta-caryophyllene and ocimene inject spice and green, slightly tropical accents.
The bouquet intensifies notably in a jar after proper curing at 58–62% relative humidity. Over a 2–4 week cure, volatile notes even out and incense tones blossom, aligning aroma with flavor more tightly. In well-cured samples, the scent holds in a room long after grinding, outperforming many hybrids in persistence.
Compared with Amnesia Haze, the original Amnesia can present slightly less overt sweetness and a touch more herbal-woody complexity. That nuance is part of its charm for purists who prize the classic, almost cathedral-incense Haze perfume. Still, citrus remains a through line, giving the strain its unmistakably uplifting nose.
Flavor Profile and Aftertaste
On the palate, Amnesia bursts with lemon peel, sweet herbs, and a fine, woody-spice finish. The inhale tends to be bright and crisp, with terpinolene and limonene leading a zesty front end. As the vapor lingers, cardamom, lemongrass, and hints of green tea emerge.
The exhale brings a return of cedar and light pepper, likely linked to beta-caryophyllene and humulene. In some phenotypes, a faint tropical echo—think mango rind or green guava—shows up, a nod to the broader Haze family. With proper curing, the flavor holds consistent across sessions and resists harshness.
Water-cured or overdried samples risk losing the top-end citrus sparkle, so careful post-harvest handling is critical. Targeting 60–62% RH during curing amplifies the lemon-herbal interplay and preserves the incense core. Many connoisseurs note that flavor expression improves markedly between days 10 and 21 of cure.
When combusted, Amnesia remains relatively smooth for a high-terpene sativa, provided it was flushed and dried correctly. Vaporization at 170–185°C (338–365°F) showcases the brighter terpenes, while 190–200°C (374–392°F) unlocks deeper spice and woody tones. That range allows tasters to tailor sessions for either zest-forward or incense-forward experiences.
Cannabinoid Profile and Potency Metrics
Lab results and market listings consistently place Amnesia in the high-THC, low-CBD category. Typical THC values range from 18% to 26% by dry weight, with well-grown indoor samples often clustering around 20–24%. CBD commonly tests below 1%, and many cuts register under 0.2%.
Minor cannabinoids appear in trace to modest amounts depending on phenotype and cultivation. CBG often falls between 0.3% and 1.0%, while THCV may be detectable in small quantities (approximately 0.1–0.5%). Total cannabinoid content frequently lands in the 20–28% range, reflecting the strain’s resin-heavy expression.
These numbers align with user reports of strong psychoactivity and limited body sedation. On platforms that aggregate consumer experiences, Amnesia repeatedly shows as energizing, creative, euphoric, and talkative, consistent with high-THC sativa profiles. Correspondingly, common side effects include dry mouth, occasional dizziness, and anxiety or paranoia in sensitive users.
For dosing, a conservative approach emphasizes small initial inhalations or low milligram edible servings (e.g., 1–2 mg THC for new consumers). Acute effects from inhalation typically onset within 2–5 minutes, peak by 30–60 minutes, and persist for 2–3 hours. Edible onset varies widely (30–120 minutes), so patience is key to avoiding unintentional overconsumption.
Terpene Profile and How It Shapes the High
Amnesia’s terpene fingerprint is strongly Haze-coded, with terpinolene often in the driver’s seat. In well-grown samples, total terpene content typically ranges from 1.5% to 3.0% by weight, occasionally higher under optimized conditions. Within that, terpinolene can account for roughly 20–35% of the terpene fraction, translating to about 0.3–0.8% w/w.
Limonene commonly follows, ranging around 0.2–0.6% w/w, delivering sharp citrus lift and elevated mood tone. Myrcene varies more widely (0.1–0.5% w/w), smoothing edges and adding gentle earth or fruit. Beta-caryophyllene (0.1–0.4% w/w) contributes pepper-spice while engaging CB2 receptors, potentially modulating inflammation pathways.
Ocimene and humulene appear as supporting players, rounding herbaceous and woody notes while subtly influencing the strain’s energetic character. The overall bouquet and experiential arc fit the broader Leafly-documented trend for Haze-family cultivars, whose terpinolene-forward stacks relate to euphoric, uplifting effects. In combination with high THC, this terpene array steers Amnesia toward alert, talkative, and creative experiences.
Because terpene ratios shift with environment and curing, flavor and effect can subtly differ between growers and harvests. Warmer rooms tend to volatilize terpenes more aggressively, risking a flatter profile if drying conditions are not carefully managed. Maintaining cool, stable post-harvest conditions preserves the lemon-incense identity that defines Amnesia.
Experiential Effects, Onset, and Side Effects
Amnesia is renowned for an upbeat, cerebral launch that many describe as clear and inspired. Within minutes of inhalation, users often report an increase in focus, idea fluency, and social ease. The mood lift is pronounced, with giggly, euphoric, and talkative states common across consumer reviews.
At moderate doses, the strain excels for daytime activities that benefit from verbal fluency or lateral thinking. Artists, designers, and writers frequently cite Amnesia for breaking creative bottlenecks without heavy sedation. Paired with music or outdoor walks, the effect profile tends to feel bright and kinetic rather than racy or jittery.
At higher doses, the sharp THC edge can tip into racing thoughts or mild paranoia, especially for those sensitive to strong sativas. Reported negatives include dry mouth, occasional dizziness, and anxiety, consistent with data aggregated for Haze-family strains. Hydration, pacing, and a comfortable environment mitigate many of these reactions.
Inhaled effects typically begin within 2–5 minutes, crest between 30–60 minutes, and taper over 2–3 hours. Edible formats extend duration substantially and should be approached with caution due to delayed onset. As with any high-THC cultivar, incremental dosing remains the best strategy to find the sweet spot between energizing clarity and overintensity.
Potential Medical Applications and Considerations
Amnesia’s uplifting profile and high THC make it a candidate for daytime mood support in some patients. Users anecdotally report benefits for stress reduction, depressive symptoms, and fatigue-related motivational deficits. The creative, talkative tilt may also help with social anxiety in low doses, though higher doses can aggravate anxiety in others.
The National Academies (2017) found substantial evidence that cannabis is effective for chronic pain in adults and as an antiemetic in chemotherapy-induced nausea and vomiting. While that evidence is not strain-specific, Amnesia’s beta-caryophyllene content and THC potency align with some users’ reports of mild analgesia. Because CBD is typically minimal (<1%), patients seeking anti-anxiety or anticonvulsant effects often pair Amnesia with CBD-rich products to balance tone.
For attention-related challenges, some consumers find the energized clarity conducive to task engagement. However, responses vary widely, and overstimulation can be counterproductive for certain neurotypes. Microdosing strategies—one or two small inhalations per session—can help individuals assess tolerability.
Medical use should always be personalized, legal, and clinician-informed. Individuals with a history of panic or psychosis, or those sensitive to stimulatory cannabis effects, may prefer lower-THC or higher-CBD alternatives. Anyone new to high-THC sativas should start low, go slow, and document responses to dial in dose and timing.
Comprehensive Cultivation Guide for Amnesia
Amnesia is a vigorous, mostly sativa cultivar that thrives under strong light and disciplined canopy management. Indoors, plants commonly reach 120–180 cm without training and can double or triple in height during the “stretch” after the flip. Outdoors, heights of 200–300 cm are attainable in warm, sunny climates, provided sufficient root volume and nutrition.
Flowering time typically runs 9–10 weeks for the original Amnesia, shorter than many extended-bloom Hazes. Under optimized indoor conditions, yields of 500–650 g/m² are achievable, with experienced growers occasionally exceeding 700 g/m² using CO2 enrichment and SCROG. Outdoor plants can deliver 600–1500 g per plant depending on season length, cultivar vigor, and pest pressure.
Environmentally, Amnesia performs best at daytime temps of 24–28°C and nighttime temps of 18–22°C. Relative humidity targets of 60–70% in veg and 40–50% in bloom are recommended, tapering to 35–45% in late flower to protect against botrytis. VPD ranges of 0.8–1.2 kPa in veg and 1.2–1.5 kPa in bloom maintain strong transpiration without undue stress.
For lighting, aim for PPFD of 600–900 µmol/m²/s in late veg and 900–1200 µmol/m²/s in bloom for photoperiod plants. With supplemental CO2 (1,100–1,300 ppm), PPFD of 1,200–1,500 µmol/m²/s is feasible, but watch for heat and nutrient uptake limits. Maintain appropriate canopy distance to prevent light bleaching; grower anecdotes from Amnesia Haze autoflower runs note tall top growth reaching fixtures and experiencing mild light burn when left unmanaged.
Nutritionally, Amnesia appreciates steady but not excessive feeding. In hydro or coco, many growers target EC 1.2–1.6 in veg and 1.8–2.2 in bloom, with pH of 5.8–6.2. In soil, a pH of 6.2–6.8 supports micronutrient availability, and living soil or amended organics can express fuller terpene complexity.
Nitrogen demand is moderate to high in veg, but sativa-leaning phenotypes may appear “hungry” without actually needing heavy inputs. Watch leaf color and petiole striping to avoid overfeeding—a common pitfall with vigorous Hazes. In bloom, prioritize phosphorus and potassium while tapering nitrogen by weeks 3–4 to encourage dense, aromatic flowers.
Training is essential for height control and yield optimization. Topping at the 4th or 5th node, followed by low-stress training (LST) and a wide screen-of-green (SCROG), spreads growth across the plane of light. This approach reduces popcorn buds, improves airflow, and helps manage the cultivar’s strong apical drive.
Expect a 1.5–3.0× stretch in the first three weeks after 12/12, depending on environment and phenotype. Install trellis layers early and be ready to tuck aggressively every 2–3 days during peak stretch. After week 4 of bloom, vertical growth slows, and attention shifts to defoliation for airflow and light penetration.
Defoliation should be measured, as excessive leaf removal can shock sativa-leaning plants. A light pass at day 21 and a second, gentler cleanup around day 42 often balance canopy density and photosynthetic capacity. Keep lower sites pruned to channel energy into top colas, aiming for uniform tops under the screen.
Irrigation strategy benefits from frequent, moderate volumes. In coco, daily or multiple daily irrigations at high frequency keep root zones oxygenated, especially at peak transpiration. In soil, thorough watering followed by near-complete dryback prevents root pathogen risk while strengthening plant structure.
Integrated pest management (IPM) should anticipate common threats like spider mites, thrips, and powdery mildew. Preventive measures—HEPA intake filtration, cleanroom practices, and weekly scouting—are your first line of defense. Biological controls such as Phytoseiulus persimilis (for mites) and Amblyseius cucumeris (for thrips) integrate well with low-toxicity protocols.
Harvest timing is critical for flavor and effect. Many growers cut Amnesia when trichomes show roughly 5–10% amber, 60–70% cloudy, and the balance clear, typically around weeks 9–10 of bloom. Earlier pulls emphasize a sharper, more electric high; later harvests add a touch of body and relax the top-end intensity.
Post-harvest handling determines whether the lemon-incense signature shines. Dry at 16–20°C (60–68°F) and 55–62% RH for 10–14 days with gentle air exchange to protect terpenes. After drying, cure in sealed jars or bins at 60–62% RH, burping daily for the first week, then weekly for 3–4 weeks to stabilize moisture and develop complexity.
For autoflower variants derived from the Amnesia line, plan for 10–12 weeks seed-to-harvest. Autos can grow unexpectedly tall, mirroring reports of Amnesia Haze autos that required tie-downs to avoid light burn. Minimize transplant stress, use LST rather than heavy topping, and maintain consistent 18–20 hours of light daily.
Yield optimization hinges on uniform canopies, steady climate, and rigorous quality control. In dialed indoor runs, it’s realistic to average 1.0–1.5 grams per watt with high-efficiency LEDs and CO2, assuming excellent environmental control and a mature SCROG. Outdoors, choose full sun, well-draining soil, and a prophylactic IPM cadence to deliver kilogram-scale plants in hospitable climates.
Finally, keep meticulous logs of irrigation, EC/pH, climate, and training interventions. Amnesia rewards iterative refinement; small adjustments in VPD, feed strength, or defoliation timing can materially alter terpene expression and flower density. Over a few cycles, most growers tame its height, amplify its yield, and lock in its signature lemon-incense brilliance.
