1.       What Are Terpenes?

Terpenes are volatile organic compounds produced by plants, including cannabis, to attract pollinators, repel pests, and protect against environmental stress. Over 20,000 terpenes exist in nature, with around 200 found in cannabis (NCBI, 2021).

Key Characteristics of Terpenes:

✔ Responsible for aroma & flavour – From fruity to woody, terpenes define a strain’s scent.
✔ May have therapeutic benefits – Some terpenes have anti-inflammatory, anti-anxiety, or sedative properties.
✔ Work synergistically with cannabinoids – They can enhance or modify the effects of THC and CBD.

✅Definition and Origins

Terpenes are organic compounds found in a wide variety of plants, including fruits, herbs, and flowers. They are responsible for the distinct aromas and flavors associated with different plants. For example, the citrusy scent of lemons comes from the terpene limonene, while the earthy aroma of pine trees is due to pinene.

These compounds are produced in the trichomes (tiny resin glands) of plants and serve as a natural defense mechanism against pests and environmental stressors. Interestingly, terpenes are also found in cannabis, where they contribute to the plant's unique scent and effects.

However, terpenes are not exclusive to cannabis—they are found in countless other plants, including:

• Citrus fruits (limonene)
• Lavender (linalool)
• Pine trees (pinene)
• Mint (menthol)

The extraction of terpenes for use in vaping products typically involves steam distillation or cold pressing, ensuring that the compounds retain their natural properties. These extracted terpenes are then carefully blended into e-liquids to create a wide range of flavours.

✅Role in Plant Biology

In nature, terpenes play a crucial role in plant survival. They attract pollinators, repel predators, and even help plants recover from damage. For humans, terpenes have been used for centuries in aromatherapy, traditional medicine, and as natural flavorings in food and beverages.

Terpenes are not just there to make plants smell good; they serve several critical functions in plant biology. Here’s a closer look at their roles:

·         Defence Mechanisms

One of the primary functions of terpenes is to protect plants from predators and environmental stressors. Some terpenes have bitter or unpleasant tastes that deter herbivores from eating the plant. Others act as natural pesticides, repelling insects or even killing fungi and bacteria. For example, the terpene limonene, found in citrus peels, is known to repel certain pests.

·         Attracting Pollinators

While terpenes can repel harmful organisms, they also play a key role in attracting beneficial ones. Many plants produce terpenes to lure pollinators like bees, butterflies, and birds. The sweet, floral scents of terpenes such as linalool (found in lavender) or myrcene (found in mangoes) are irresistible to these creatures, ensuring the plant’s reproduction and survival.

·         Adaptation to Environmental Stress

Terpenes help plants adapt to their environment. For instance, some terpenes act as antioxidants, protecting plants from damage caused by UV radiation or pollution. Others help regulate the plant’s internal temperature by evaporating and cooling the surface of leaves during hot weather.

·         Communication Between Plants

Interestingly, terpenes also facilitate communication between plants. When a plant is under attack—say, by insects—it can release terpenes into the air to signal nearby plants. These neighbouring plants then produce their own defensive compounds in response, creating a kind of “plant immune system.”

Terpenes are hydrocarbons, meaning they are composed of hydrogen and carbon atoms. They are synthesized in plants through the mevalonic acid pathway or the methylerythritol phosphate (MEP) pathway. These pathways produce isoprene units, which combine to form terpenes. The diversity of terpenes arises from the different ways these units can be arranged.

For example, monoterpenes (like limonene) consist of two isoprene units, while sesquiterpenes (like caryophyllene) consist of three. This structural diversity is what gives terpenes their wide range of aromas and effects.

Terpenes are not just limited to vaping or cannabis; they are everywhere in our daily lives. The refreshing scent of a pine forest, the calming aroma of lavender, and the zesty smell of citrus fruits are all due to terpenes. They are also used in essential oils, perfumes, and even cleaning products for their aromatic properties.

2.       Why Terpenes Matter in the Vape Industry

The UK's CBD and wellness markets are evolving fast, and consumers are becoming more discerning than ever. In 2025, it’s not just about THC and CBD levels—it's about entourage effect, personalisation, and lab-verified terpene profiles.

With Hempire Gardens and HG Terpenes leading innovation in terpene formulations, British users now have access to strain-specific terpene blends that enhance mental clarity, physical recovery, or restful sleep.

Additionally, the UK Food Standards Agency (FSA) has introduced more stringent guidelines for products containing botanical extracts. These include clear labeling, third-party testing, and novel food authorisation—making scientific literacy around terpenes essential.

✅The UK Vape Market in 2025: Trends & Regulations

A. Current UK Vape Laws (2025 Update)

• Nicotine Vapes: Still legal but under stricter marketing & packaging rules (plain packaging, flavour restrictions for disposables).
• CBD Vapes: Fully legal if derived from EU-approved hemp strains (<0.2% THC).
• THC Vapes: Only legal for medical cannabis patients (recreational use remains prohibited).

B. Rising Demand for Terpene-Rich Vapes

• Consumers want authentic, natural flavours (not just synthetic sweeteners).
• Wellness-focused vapers seek terpenes for potential calming or energising effects.
• Disposable vape decline (due to environmental concerns) has boosted refillable terpene-based e-liquids.

C. The Role of Terpenes in Compliance

With flavour bans looming for some nicotine products, terpenes offer a natural, compliant alternative to synthetic additives.

✅The Science of Terpenes in Vaping

A. How Terpenes Work When Vaped

When heated, terpenes vaporise at different temperatures, releasing their flavour and potential benefits.

• Limonene (citrusy) vaporises at 176°C
• Myrcene (earthy) at 166°C
• Pinene (pine-like) at 155°C

A study in Scientific Reports (source) found that properly heated terpenes retain their properties better than combustion (smoking).

B. Bioavailability & Absorption

• Vaping allows terpenes to enter the bloodstream quickly via the lungs.
• Some terpenes (like β-Caryophyllene) even interact with the endocannabinoid system (source: British Journal of Pharmacology).

✅How Terpenes Enhance the Vaping Experience

A. Flavour Customisation

UK brands now use terpenes to recreate classic cannabis strains (e.g., Blue Dream, OG Kush) or unique blends (e.g., tropical, minty).

B. Effect Modulation

• Relaxation: Linalool (lavender), Myrcene (mango)
• Focus: Pinene (pine), Terpinolene (fresh herbs)
• Mood Boost: Limonene (citrus), β-Caryophyllene (peppery)

C. Smoothness & Throat Hit

Well-balanced terpenes can reduce harshness—key for ex-smokers switching to vaping.

3.       Types of Terpenes and Their Effects

✅Major Terpenes in the UK Market (2025 Update)

Myrcene: The Relaxation Terpene

• Aroma: Earthy, musky (similar to cloves)
• Effects: Sedating, muscle-relaxing
• Found in: Mangoes, thyme, cannabis (especially indica strains)

• Stay updated on UK regulatory changes

4.       Cannabis-Derived vs. Botanical Terpenes

✅Defining the Key Terms

Cannabis-Derived Terpenes (CDTs)

• Extracted directly from cannabis plants
• Contain the full spectrum of a strain's natural terpene profile
• Preserve strain-specific characteristics
• Typically more expensive to produce

Botanical Terpenes (BTs)

• Sourced from non-cannabis plants (citrus, lavender, pine, etc.)
• Often isolated and blended to mimic cannabis profiles
• Generally more cost-effective
• Wider range of legal applications

A 2024 study in the Journal of Cannabis Research (source) found that while both types share molecular structures, their effects can differ due to entourage factors.

✅Extraction Methods: Technology Advancements in 2025

CDT Extraction Techniques

1)      Steam Distillation (Most common, preserves delicate terpenes)

2)      Hydrocarbon Extraction (Higher yields but requires purification)

3)      CO2 Extraction (Clean but expensive, gaining popularity)

4)      Cold Separation (New in 2025, preserves volatile compounds)

BT Extraction Methods

1)      Fractional Distillation (Precise isolation of single terpenes)

2)      Expression (Mechanical, mainly for citrus peels)

3)      Molecular Isolation (Advanced chromatography techniques)

The UK's Medicinal Cannabis Industry Association now recommends CO2 methods for medical-grade CDTs.

✅Sensory and Therapeutic Comparisons

Flavor Profiles

• CDTs: Offer authentic "strain-specific" experiences
• Example: OG Kush CDTs replicate the exact earthy-pine taste
• BTs: Can achieve similar profiles but often lack depth
• Example: Myrcene from mango vs. cannabis shows subtle differences

Therapeutic Effects

A 2025 University of Edinburgh study compared:

Effect	CDTs	BTs
Pain Relief	23% more effective	Standard efficacy
Anxiety Reduction	Lasted 2 hours longer	Short-term effects
Sleep Quality	Improved onset time	Comparable to placebo

 

✅Market Trends and Consumer Preferences

UK Market Share (2025)

• CDTs: 38% of cannabis products (up from 22% in 2022)

5.       Terpenes and the Entourage Effect

✅Defining the Entourage Effect in 2025

The Core Concept

First proposed by Dr. Ethan Russo in 2011, the entourage effect describes how minor cannabis compounds modulate the effects of primary cannabinoids like THC and CBD. A 2024 meta-analysis in Nature Neuroscience (source) confirmed this interaction occurs through:

• Pharmacokinetic modulation (changing how compounds are absorbed)
• Pharmacodynamic enhancement (altering receptor binding)
• Blood-brain barrier permeability (facilitating neural access)

UK-Specific Findings

The 2025 Imperial College London Medical Cannabis Review identified three key entourage mechanisms:

1)      Terpene-mediated cannabinoid deceleration (Myrcene extends THC duration)

2)      Receptor allosteric modulation (Linalool enhances CB1 sensitivity)

3)      Neurotransmitter co-release (Pinene boosts acetylcholine with CBD)

7.       Legal Considerations for Terpenes in the UK

✅Legal Classification of Terpenes in 2025

Three Regulatory Categories

The UK now classifies terpenes based on source and application:

Category	Definition	Governing Body
Food-Grade Terpenes	Isolated from non-cannabis plants	FSA
Cannabis-Derived	Extracted from cannabis plants	Home Office/MHRA
Synthetic/Analogues	Laboratory-created compounds	Banned since Jan 2025

A 2025 parliamentary review confirmed this tripartite system, with cannabis-derived terpenes (CDTs) facing the strictest controls.

✅Novel Food Regulations: The 2025 Update

Key Requirements

• Full authorization required for ingestible products
• Toxicological assessments for all terpene blends
• Maximum limits for individual terpenes (e.g., myrcene <5mg/day)
• Stability testing under various conditions

HG Terpenes achieved full Novel Food status in March 2025 after demonstrating exceptional stability profiles across 23 test parameters.

✅Medical vs. Recreational Distinctions

Medical Cannabis Terpenes

• Prescription-only status
• Require GMP certification
• Dose-specific packaging
• NICE guidelines now include terpene ratios

Recreational CBD Terpenes

• THC content must be <0.2%
• No medical claims permitted
• Flavor descriptors limited to approved lexicon

The Medicines and Healthcare products Regulatory Agency (MHRA) recently fined three companies £420,000 total for making unauthorized medical claims about terpene products.

✅THC Content and Psychoactivity Thresholds

2025 Compliance Standards

• Total THC (including precursors): ≤0.3%
• Individual terpene thresholds:
• Myrcene: ≤7% of total product
• Pinene: ≤5% of total product
• Limonene: ≤10% of total product

A University of Bath study (source) found these limits prevent unintended psychoactive effects while preserving therapeutic benefits.

✅Packaging and Labelling Mandates

Required Elements

1)      Terpene percentage by weight

2)      Full ingredient disclosure

3)      Batch-specific QR code

4)      Child-resistant mechanisms

5)      Allergen warnings (e.g., citrus-derived limonene)

Non-compliant example (fine: £5,000):
"Contains natural terpenes for relaxation"

Compliant alternative:
"Botanical terpene blend (3.2% total): Myrcene (1.8%), Pinene (0.9%), Limonene (0.5%). Not for medical use. Contains citrus derivatives."

✅Import/Export Considerations

Brexit-Related Changes

• EU-grown cannabis terpenes now require Schedule 1 licenses
• Non-CDT imports must show phytosanitary certificates
• Export controls apply to terpenes above 1% concentration

The UK Terpene Trade Association reports 37% longer clearance times for CDT imports compared to 2024.

✅Future Regulatory Projections

2026-2027 Outlook

1)      Terpene-specific excise duties (projected 5-8% levy)

2)      Enhanced track-and-trace (blockchain integration)

3)      Psychoactivity scoring system (under MHRA review)

4)      Sustainability requirements for cultivation/extraction

HG Terpenes' regulatory team predicts full legalization of recreational CDT products by Q3 2027, following the German model.
