Relax & CBD Liquids

CBD liquid is a cannabinoid format for inhalation, made for use with any open tank vaporiser. This collection brings together seven carefully selected CBD e-liquids, formulated for smooth vapour and consistent flavour. Whether you are new to vaping CBD or looking to refine your setup, this range covers the concentrations and flavour profiles most in demand.

CBD e-liquids for open tank vaporisers

All liquids in this collection are designed for open tank systems, also known as sub-ohm or refillable vape tanks. This means you fill your own device rather than using a sealed cartridge or disposable pen. The advantage is straightforward: lower cost per millilitre, full control over your hardware, and the ability to mix concentrations to suit your preference.

CBD e-liquids use a PG/VG (propylene glycol / vegetable glycerin) base, which produces a smooth, consistent vapour. The active compounds are suspended evenly throughout the liquid, so every puff delivers a stable amount. Unlike carrier oils used in oral drops, PG/VG bases are formulated specifically for vaporisation and are not suited to oral use.

If you prefer a ready-to-use closed system instead, the CBD vapes collection and the CBD pen cartridges offer pre-filled options that require no refilling or technical setup.

CBD liquid vs CBD oil: key differences

CBD liquid and CBD oil are two distinct products designed for different routes of use. Understanding the difference helps you choose the format that fits your routine.

• CBD liquid uses a PG/VG base and is intended for vaporisation only. It heats quickly at low temperatures and produces inhalable vapour.
• CBD oil uses a carrier oil (such as hemp seed oil or MCT oil) and is designed for oral or sublingual use. It is never suitable for vaporisation because carrier oils break down into harmful compounds when heated.
• Route of use differs. CBD liquid is inhaled through a vaporiser. CBD oil is taken by mouth.
• Concentration labelling also works differently. CBD oils are typically labelled by total milligrams per bottle. CBD liquids are more commonly labelled by percentage concentration per millilitre, for example 300 mg/10 ml = 3%.

For oral CBD formats, the CBD oils and ointments collection covers drops, capsules, and topical products separately.

How to choose the right CBD liquid concentration

Concentration is the most practical decision when selecting a CBD liquid. The range in this collection covers low, mid, and higher strength options, which broadly correspond to different usage patterns and levels of familiarity with CBD vaping.

Lower concentrations (around 1-3%) suit those who vape often during the day. They are also a sensible starting point if you have not vaped CBD before. Mid-range concentrations (around 4-6%) are the most versatile, working well for regular use with a standard open tank device. Higher concentrations (10% and above) are typically chosen by experienced users who vape less frequently and prefer fewer, shorter sessions.

Device settings also play a role. A sub-ohm tank running at higher wattage will vaporise more liquid per puff than a standard mouth-to-lung coil at lower wattage. If you are unsure, start with a mid-range concentration and adjust based on your experience over the first few days.

Flavour is a secondary but real consideration. CBD liquids in this collection are available in both natural hemp profiles and more neutral or fruit-forward options. The underlying cannabinoid profile does not change with flavour, so this is purely a personal preference.

Lab testing of CBD liquids

Every CBD liquid in this collection is tested by independent third-party laboratories. Lab reports confirm cannabinoid content, verify the absence of pesticides and heavy metals, and document the levels of active compounds present. Certificates of analysis are available on individual product pages.
