Capers is an indica-dominant hybrid cannabis strain with a strong lineage potentially tracing back to Burmese Kush. This strain is known for its high myrcene content, moderate-to-high THC levels (14%-19%), and strong sedative effects, making it particularly valuable for therapeutic use and evening relaxation.
This article explores Capers from a scientific and medical perspective, detailing its cannabinoid and terpene profile, pharmacodynamics, potential medical applications, neurophysiological effects, and cultivation characteristics.
Genetic and Phytochemical Composition
Capers is a predominantly indica strain (90% indica, 10% sativa). While its precise breeding lineage is not fully documented, it is believed to descend from Burmese Kush, which itself is a cross between a Burmese landrace strain and OG Kush.
Cannabinoid Composition
Capers has a moderate-to-high THC content and a diverse range of secondary cannabinoids, including CBD, CBG, and CBC in minor amounts.
| Cannabinoid | Typical Concentration | Effects |
|---|---|---|
| Δ9-THC | 14%-19% | Psychoactive, analgesic, sedative |
| CBD | <1% | Anxiolytic, neuroprotective |
| CBG | 0.5%-1% | Anti-inflammatory, neuroprotective |
| CBC | <0.5% | Analgesic, anti-depressant |
- Δ9-THC (Tetrahydrocannabinol): Capers’ high THC content induces euphoria, deep muscle relaxation, and sedation.
- CBD (Cannabidiol): The low CBD content suggests that Capers is not primarily used for non-psychoactive relief, but it may still contribute to anti-inflammatory and anxiolytic properties.
- CBG (Cannabigerol): Present in low concentrations, but contributes to neuroprotection and anti-inflammatory effects.
- CBC (Cannabichromene): Works synergistically with THC and CBG for pain relief.
Terpene Profile and Entourage Effect
Terpenes modulate Capers’ psychoactive and therapeutic effects via the entourage effect—where cannabinoids and terpenes synergistically enhance efficacy.
| Terpene | Percentage | Effects | Aroma |
|---|---|---|---|
| Myrcene | 0.5%-1.5% | Sedative, muscle relaxant | Earthy, musky |
| Pinene | 0.2%-0.5% | Anti-inflammatory, bronchodilator | Pine, herbal |
| Caryophyllene | 0.3%-0.7% | Analgesic, anti-anxiety | Spicy, woody |
| Limonene | 0.1%-0.3% | Mood-enhancing, anti-depressant | Citrus, lemon |
- Myrcene: The dominant terpene, known for its sedative and muscle-relaxing effects. In synergy with THC, it enhances the “couch-lock” effect.
- Pinene: May counteract memory impairment induced by THC and help with bronchodilation.
- Caryophyllene: Interacts with the CB2 receptors, contributing to anti-inflammatory and anxiolytic properties.
- Limonene: Helps counterbalance the potential anxiety-inducing effects of THC, promoting an uplifting experience.
Pharmacodynamics and Neurophysiological Effects
Capers affects multiple neurochemical pathways in the endocannabinoid system (ECS), particularly the CB1 and CB2 receptors.
Interaction with the Endocannabinoid System (ECS)
Capers’ cannabinoids interact with endogenous cannabinoid receptors (CB1 and CB2) in different ways:
- CB1 Receptor (Central Nervous System) Activation:
- Δ9-THC binds agonistically to CB1 receptors in the hippocampus, prefrontal cortex, and basal ganglia, inducing:
- Euphoria (dopaminergic activity in nucleus accumbens)
- Short-term memory suppression (hippocampal effects)
- Pain relief (modulation of nociceptive pathways)
- Sleep induction (modulation of hypothalamic sleep centers)
- Δ9-THC binds agonistically to CB1 receptors in the hippocampus, prefrontal cortex, and basal ganglia, inducing:
- CB2 Receptor (Peripheral Nervous System) Activation:
- While THC has low CB2 affinity, caryophyllene interacts directly with CB2 receptors, exerting:
- Anti-inflammatory effects
- Potential immunomodulation
- Analgesic properties in chronic pain models
- While THC has low CB2 affinity, caryophyllene interacts directly with CB2 receptors, exerting:
Effects on Neurotransmitter Systems
Capers modulates neurotransmitter release by influencing:
- Dopaminergic System: Increases dopamine release in the mesolimbic system, leading to euphoria and stress relief.
- GABAergic System: Enhances GABAergic inhibition, reducing neuronal excitability, which contributes to anti-anxiety and sedative properties.
- Glutamatergic System: Suppresses glutamate release, reducing excess neuronal excitability, leading to muscle relaxation and pain relief.
Medical Applications of Capers Strain
Capers is widely used in medical cannabis programs for conditions related to chronic pain, neurological disorders, and sleep disturbances.

- Crohn’s disease
Capers cannabis strain, like all cannabis varieties, has multiple ingestion methods that impact onset time, duration, and intensity of effects. Understanding the pharmacokinetics (absorption, distribution, metabolism, and excretion) of Capers allows for precise dosing and therapeutic optimization.
1. Methods of Ingestion and Their Pharmacokinetics
The method of consumption directly influences:
- Onset of effects (how quickly it takes effect)
- Duration of effects (how long the high lasts)
- Bioavailability (how much THC enters the bloodstream)
| Method of Ingestion | Onset Time | Peak Effects | Duration | Bioavailability (%) |
|---|---|---|---|---|
| Smoking (Combustion) | 1-5 minutes | 20-30 minutes | 2-4 hours | 20-37% |
| Vaporization | 1-5 minutes | 15-30 minutes | 2-4 hours | 30-50% |
| Edibles | 30-90 minutes | 2-4 hours | 6-8 hours | 4-20% |
| Sublingual (Tinctures, Sprays) | 10-20 minutes | 30-60 minutes | 4-6 hours | 40-50% |
| Transdermal Patches | 15-60 minutes | 2-3 hours | 8-12 hours | 40-70% |
| Suppositories | 10-30 minutes | 1-2 hours | 4-8 hours | 50-70% |
2. Inhalation Methods: Smoking vs. Vaporization
2.1 Smoking (Combustion)
This method involves burning cannabis (joints, pipes, bongs) at temperatures between 600 and 900 degrees Celsius, leading to rapid THC absorption.

- Onset: 1-5 minutes (THC reaches peak plasma levels within 3-10 minutes).
- Bioavailability: 20-37 percent due to combustion loss and variable inhalation depth.
- Peak Effects: 20-30 minutes post-inhalation.
- Duration: 2-4 hours.
- Downsides:
- Combustion destroys approximately 40-50 percent of cannabinoids and terpenes.
- Produces harmful byproducts, including polycyclic aromatic hydrocarbons, tar, and carbon monoxide.
- Less efficient THC delivery.
2.2 Vaporization
This method uses lower temperatures (160-220 degrees Celsius) to convert cannabinoids and terpenes into vapor without combustion.
- Onset: 1-5 minutes.
- Bioavailability: 30-50 percent, making it more efficient than smoking.
- Peak Effects: 15-30 minutes.
- Duration: 2-4 hours.
- Scientific Benefits:
- Preserves up to 95 percent of cannabinoids and terpenes.
- Lower respiratory toxicity due to the absence of combustion byproducts.
- More efficient THC delivery.
Optimal vaporization temperatures:
| Cannabinoid/Terpene | Optimal Vaporization Temperature (°C) |
|---|---|
| THC | 157 |
| CBD | 160-180 |
| Myrcene | 166 |
| Limonene | 176 |
| Caryophyllene | 199 |
Scientific research suggests that vaporization is more efficient, healthier, and preserves terpenes better than smoking.
3. Oral Ingestion: Edibles vs. Sublingual Administration

3.1 Edibles (Metabolized by Liver)
THC is converted into 11-hydroxy-THC (11-OH-THC) in the liver, which is more potent and longer-lasting than inhaled THC.
- Onset: 30-90 minutes, depending on metabolism and stomach contents.
- Bioavailability: 4-20 percent due to first-pass metabolism in the liver.
- Peak Effects: 2-4 hours post-ingestion.
- Duration: 6-8 hours, but can last up to 12 hours in high doses.
Scientific Insight:
- 11-OH-THC crosses the blood-brain barrier more efficiently, causing stronger and longer-lasting psychoactive effects.
- Since THC is fat-soluble, consuming edibles with fatty foods enhances absorption.
Common Issues with Edibles:
- Unpredictable absorption due to digestion variability.
- Higher risk of overconsumption since effects take longer to kick in, leading to excessive dosing.
3.2 Sublingual Administration (Tinctures, Sprays)
The mucosal membranes beneath the mouth allow THC to enter the bloodstream immediately.

- Onset: 10-20 minutes.
- Bioavailability: 40-50 percent, higher than edibles.
- Peak Effects: 30-60 minutes.
- Duration: 4-6 hours.
Scientific Benefits:
- Bypasses first-pass metabolism, leading to faster onset and better bioavailability.
- More predictable dosing compared to edibles.
This method is particularly useful for medical applications where rapid relief is needed, such as pain, nausea, and anxiety.
4. Transdermal and Rectal Administration: Extended-Release Methods
4.1 Transdermal Patches
THC or CBD slowly diffuses through the skin into the bloodstream over several hours.
- Onset: 15-60 minutes.
- Bioavailability: 40-70 percent.
- Peak Effects: 2-3 hours.
- Duration: 8-12 hours.
Best for chronic pain, epilepsy, or long-term medicinal relief without intoxication.
4.2 Rectal Suppositories
Bypasses first-pass metabolism by absorbing THC directly into the bloodstream via the rectal mucosa.
- Onset: 10-30 minutes.
- Bioavailability: 50-70 percent.
- Peak Effects: 1-2 hours.
- Duration: 4-8 hours.
Scientific research indicates that rectal administration is more effective than edibles due to bypassing liver metabolism. It is also less psychoactive than oral THC but still provides medicinal benefits. This method is ideal for patients who cannot tolerate inhalation or oral methods, such as those undergoing chemotherapy.
5. Comparison of Onset and Duration for Different Methods
| Ingestion Method | Onset Time | Peak Effects | Duration |
|---|---|---|---|
| Smoking/Vaping | 1-5 min | 20-30 min | 2-4 hours |
| Edibles | 30-90 min | 2-4 hours | 6-8 hours |
| Sublingual (Tinctures, Sprays) | 10-20 min | 30-60 min | 4-6 hours |
| Transdermal Patches | 15-60 min | 2-3 hours | 8-12 hours |
| Rectal Suppositories | 10-30 min | 1-2 hours | 4-8 hours |
Scientific Takeaways: Best Methods for Different Needs
- For fast relief: Vaporization or smoking is best for acute pain, anxiety, and migraines.

- Synthetic nutrients (NPK blends, chelated micronutrients) → Ensure rapid absorption but may reduce microbial biodiversity.
Scientific Recommendation: Use a hybrid approach (organic base + supplemental synthetic nutrients for precision).
4. Environmental Control and Growth Optimization
4.1 Light Spectrum Manipulation
Cannabis responds differently to varied wavelengths of light. Using optimized LED or HPS grow lights improves potency and yield.
| Light Spectrum | Effect on Capers Growth |
|---|---|
| Blue (400-500 nm) | Encourages vegetative growth, enhances compact structure |
| Red (600-700 nm) | Triggers flowering, increases THC production |
| Far-Red (730 nm) | Speeds up flowering cycle by reducing photoperiod stress |
| UV-B (280-315 nm) | Enhances trichome density and cannabinoid production |
Scientific Insight: Supplementing UV-B light during late flowering increases THC and terpene production by up to 30%.
4.2 CO₂ Enrichment for Maximized Yield
Increasing CO₂ levels (1000-1500 ppm) in a controlled sealed grow room can increase Capers’ photosynthetic efficiency by ~30%, leading to larger, denser buds.
Implementation:
- Use CO₂ generators or compressed CO₂ tanks.
- Ensure high-intensity lighting (at least PPFD 800-1000 μmol/m²/s) to utilize extra CO₂ effectively.
- Avoid excessive CO₂ in flowering (above 1500 ppm can degrade terpenes).
Expected Yield Increase with CO₂: 20-35% under ideal conditions.
5. Pruning, Training, and Yield Maximization
5.1 High-Stress Training (HST) vs. Low-Stress Training (LST)
- LST (Low-Stress Training):
- Bending and tying branches without damaging plant structure.
- Improves light penetration and bud development.
- Best for indoor and SCROG (Screen of Green) setups.
- HST (High-Stress Training):
- Topping (removing apical bud) to encourage multiple colas.
- Super cropping (intentional stem bending to cause minor stress).
- Increases THC concentration due to stress-induced secondary metabolite production.
Scientific Strategy: Combine LST in early vegetative growth and HST at pre-flowering stage for maximum bud development.
6. Harvesting, Curing, and Terpene Retention
6.1 Trichome Maturity and Harvest Timing
Capers’ peak THC and terpene content is reached when trichomes transition from clear → milky white → amber.
| Trichome Color | Effect Profile | Harvest Timing |
|---|---|---|
| Clear | Underdeveloped cannabinoids | Too early |
| Milky White | Peak THC, balanced high | Ideal for maximum potency |
| Amber | Increased CBN, more sedative | Ideal for sleep-inducing effects |
6.2 Curing Process
Optimal curing (4-6 weeks in 60-65% RH, 18-22°C) is critical for preserving Capers’ terpene profile and enhancing smoothness.
Scientific Best Practices:
- Store in glass jars with burping schedule (open daily for first 2 weeks).
- Keep in dark, cool conditions to prevent terpene degradation.
- Ideal curing duration: 4-6 weeks for peak flavor and potency.
