The Active Compounds
Cannabinoids: The Engine of Effects
These compounds interact with your endocannabinoid system to produce therapeutic and psychoactive effects.
THC
Δ9-Tetrahydrocannabinol
10-30%
Primary psychoactive cannabinoid in cannabis. THC binds strongly to CB1 receptors in the brain, producing euphoria, altered perception, and appetite stimulation. Edibles convert THC to 11-OH-THC, which is more potent and produces stronger body effects.
🔬 Clinical Evidence
THC and its metabolites bind CB1 receptors in the brain, producing euphoria and analgesia. Clinical studies (2024) show that co-inhalation of low-dose limonene (1-5mg) reduces THC-induced anxiety without diminishing therapeutic benefits. CB1 receptors are the most abundant G-protein-coupled receptor in the mammalian brain.
- • Strong CB1 receptor agonist
- • Modulates neurotransmitter release
- • High CB1 density in cortical, amygdala, and basal ganglia regions
- • Metabolized to 11-OH-THC (more potent) via first-pass metabolism
CBD
Cannabidiol
0.5-20%
Non-psychoactive cannabinoid with numerous therapeutic benefits. CBD modulates cannabinoid receptor signaling indirectly and interacts with serotonin and TRPV receptors to produce anti-anxiety, anti-inflammatory, and neuroprotective effects.
🔬 Clinical Evidence
FDA-approved drug Epidiolex (pure CBD) is used to treat severe childhood epilepsies (Dravet syndrome, Lennox-Gastaut syndrome). CBD does not produce intoxication and may counteract some THC side effects through allosteric modulation of CB1 receptors.
✅ FDA Approved
Epidiolex (for epilepsy)
- • Modulates cannabinoid receptor signaling indirectly
- • Interacts with serotonin (5-HT1A) receptors
- • Activates TRPV1 (vanilloid) receptors
- • Enhances anandamide levels (FAAH inhibition)
CBG
Cannabigerol
<1% (precursor to other cannabinoids)
The "mother" or "stem cell" cannabinoid from which THC, CBD, and CBC are synthesized. CBG is usually present in low amounts (<1%) but has powerful therapeutic properties.
🔬 Clinical Evidence
2024 human clinical trial breakthrough: 20mg CBG enhanced memory recall and reduced anxiety without impairment. Preclinical studies show CBG has antibacterial activity superior to vancomycin against MRSA in mice. Also shows neuroprotective and anti-inflammatory effects.
- • Partial agonist at CB1 and CB2 receptors
- • Enhances anandamide levels
- • α2-adrenoceptor agonist
- • Superior antibacterial activity (vs. MRSA)
CBN
Cannabinol
<1% (increases with age/oxidation)
Created when THC ages or is exposed to heat/light. CBN is about 10 times less potent at CB1 receptors than THC, producing minimal intoxication but notable sedative properties.
🔬 Clinical Evidence
Preclinical studies show CBN increases non-rapid eye movement and REM sleep in rodents. The hypnotic action may result from its metabolite 11-hydroxy-CBN rather than CBN itself. Human clinical evidence is limited; a 2023 trial protocol states that robust evidence for CBN as a sleep aid is lacking, requiring more research.
- • Weak CB1 receptor agonist (~10x less potent than THC)
- • Increases non-rapid eye movement and REM sleep
- • Metabolite 11-hydroxy-CBN may be more active
- • Formed by non-enzymatic oxidation of THC
CBC
Cannabichromene
0.05-0.3%
Non-psychoactive cannabinoid synthesized from CBGA. CBC selectively activates CB2 receptors with higher efficacy than THC, leading to strong anti-inflammatory and analgesic effects without psychotropic side-effects.
🔬 Clinical Evidence
In vitro and in vivo studies show CBC reduces nitric oxide and pro-inflammatory cytokines (iNOS, IL-1β, IL-6, TNF-α) by ~50%. Inhibits NF-κB and MAPK pathways and reduces inflammation in mouse models. Because CB2 receptors are primarily on immune cells, CBC may provide targeted relief without euphoria.
- • Selectively activates CB2 receptors (higher efficacy than THC)
- • Reduces NO and pro-inflammatory cytokines by ~50%
- • Inhibits NF-κB and MAPK pathways
- • No psychotropic effects (CB2 primarily on immune cells)
THCV
Tetrahydrocannabivarin
<1% (higher in some African strains)
A homologue of THC with a shorter side chain. THCV has minimal psychoactivity at typical doses and displays unique metabolic effects including appetite suppression and enhanced energy metabolism.
🔬 Clinical Evidence
THCV acts as a CB1 receptor antagonist, leading to appetite suppression and enhanced energy metabolism. Preclinical studies show it improves insulin sensitivity, promotes glucose uptake, restores insulin signaling, reduces lipid accumulation, and enhances mitochondrial activity in adipocytes and hepatocytes. Animal models show it suppresses appetite and prevents fatty liver disease. Preliminary human trials found THCV lowers fasting plasma glucose and improves glycaemic control, making it a promising candidate for obesity and type-2 diabetes management.
- • CB1 receptor antagonist (blocks appetite stimulation)
- • Partial CB2 agonist
- • Improves insulin sensitivity
- • Enhances glucose uptake and insulin signaling
- • Reduces lipid accumulation, enhances mitochondrial activity
The Entourage Effect

The Endocannabinoid System
Your Body & Cannabis
Understanding how cannabis works in your body.
🧠 CB1 Receptors
Found primarily in the brain and central nervous system. THC binds to these receptors to produce psychoactive effects. The most abundant G-protein-coupled receptor in the mammalian brain, highly expressed in cortical, amygdala, and basal ganglia regions.
💪 CB2 Receptors
Located primarily on immune cells and peripheral organs. CBD and other cannabinoids interact with these for therapeutic effects without psychoactivity. Up-regulated on microglia during inflammation.
🔬 Fun Fact:
The endocannabinoid system was only discovered in the 1990s, making it one of the most recently identified physiological systems. Your body naturally produces compounds similar to cannabis (anandamide and 2-AG) that regulate mood, memory, appetite, pain, and immune response.
Finding Your Balance
Tolerance & Dosage
Understanding how tolerance develops and finding your optimal dose.
Tolerance Reset Timeline
Cannabis tolerance develops due to CB1 receptor down-regulation with chronic use. Recovery timeline based on PET imaging studies.
48-72 hours
Initial reset begins
→ Minimum break for slight sensitivity improvement
1-2 weeks
Significant tolerance reduction
→ Recommended break for noticeable reset
4 weeks
Near-baseline sensitivity
→ Full reset, CB1 receptor density returns to non-user levels
📚 Evidence:
PET imaging study found cannabis-dependent subjects had ~15% lower CB1 receptor availability than controls, but receptor density recovered after only 2 days of abstinence. After 28 days, there was no difference from non-users.
Dosage Guidelines
1-2.5mg THC
Subtle effects, functional for daytime use
Best for: Beginners, daily function, microdosing protocols
2.5-5mg THC
Mild euphoria and relaxation
Best for: Beginners, social use, gentle relief
5-10mg THC
Noticeable psychoactive effects and impairment
Best for: Intermediate users, evening use, pain relief
10-20mg+ THC
Strong effects and significant impairment
Best for: Experienced users only, high tolerance, severe symptoms
⚠️ Always start low and go slow, especially with edibles. You can take more, but you can't take less.
Common Questions
Frequently Asked Questions
Everything you need to know about cannabis science and effects.
What is the entourage effect? ▼
The entourage effect is the theory that cannabis compounds work better together than in isolation. Terpenes, cannabinoids, and other compounds create synergistic effects that enhance therapeutic benefits. For example, limonene can reduce THC-induced anxiety without diminishing therapeutic effects.
How do terpenes influence my high? ▼
Terpenes modulate neurotransmitters and receptor activity. Myrcene enhances sedation via TRPV1 and opioid pathways, while limonene reduces anxiety via adenosine A2A receptors. Knowing a strain's terpene profile offers better prediction of effects than broad 'indica/sativa' labels.
Why do the same strains affect people differently? ▼
Individual differences in endocannabinoid system, metabolism, tolerance, body chemistry, and even mood all affect how cannabis impacts you. Genetic polymorphisms in CB1 receptors, enzyme activity, and differences in body fat alter absorption and clearance.
How does the High Spectrum™ relate to Sativa/Indica? ▼
The High Spectrum™ is an enhancement, not a replacement. Sativa/Indica/Hybrid tells you about plant structure. The High Spectrum™ adds a layer of precision by mapping strains by their chemistry (cannabinoid ratios and terpene profiles) to predict effects more accurately.
How long does tolerance take to reset? ▼
CB1 receptors begin to recover within 48-72 hours of abstinence. Significant tolerance reduction occurs after 1-2 weeks, and near-baseline sensitivity returns by four weeks. Periodic breaks and microdosing help maintain sensitivity.
