Once you are comfortable with the basics, there is a deeper layer to vaping: device types beyond pods and disposables, e-liquid ratios, coil options, battery safety and techniques for tuning flavour and vapour. This guide is a factual overview for experienced adult vapers in Canada.
Adults 19+ only. Vaping products contain nicotine, which is addictive. Battery safety information below is general guidance - follow manufacturer instructions for your specific device.
Device Types Beyond Basics
- Pod systems: Compact and simple. Good for nicotine salts and portability. Examples: STLTH Device Type C, Geekvape Wenax Q Pro. See our pod systems.
- Vape pens: Slim, pen-shaped devices with larger batteries than cigalikes. Simple operation with modest power.
- Box mods (regulated): Larger devices with adjustable wattage, temperature control and replaceable batteries. Paired with sub-ohm tanks or rebuildable atomizers for the most customization.
- Mechanical mods (unregulated): No circuitry or protections - the battery connects directly to the coil. These require thorough knowledge of Ohm's law and battery safety, and are only for highly experienced users.
E-Liquid: PG/VG Ratios and Nicotine
PG vs. VG
- Propylene glycol (PG): Thinner, carries flavour well, stronger throat feel. Suits mouth-to-lung vaping and pod systems.
- Vegetable glycerin (VG): Thicker, produces denser vapour, smoother draw. Suits direct-to-lung vaping and higher-power devices.
Common ratios:
- 50/50: Balanced. Works well in pod systems and MTL setups.
- 70/30 VG/PG: Denser vapour. Popular for sub-ohm tanks.
- Max VG: Thickest vapour, mildest throat feel. Used by cloud-focused vapers with suitable hardware.
Nicotine Strengths
- 20 mg/mL: Canada's federal maximum. Standard in disposables and pod systems (usually nicotine salt formulation).
- 10-12 mg/mL: Available in some bottled e-liquids.
- 3-6 mg/mL: Typical for sub-ohm devices, where higher vapour volume delivers nicotine efficiently at lower concentrations.
- 0 mg/mL: Nicotine-free options.
Nicotine salts feel smoother at higher strengths; freebase nicotine is standard at lower strengths for sub-ohm use.
Coils: Types and Maintenance
- Stock coils: Pre-built replaceable coils for tanks and pods. Choose the resistance that matches your device and preferred style (higher resistance for MTL, lower for DTL).
- Mesh coils: A mesh strip instead of wound wire, heating more evenly for consistent flavour. Common in modern sub-ohm tanks and many pod systems.
- Rebuildable coils: For RDAs, RTAs and RDTAs - the user wraps and installs their own coils and wicking. Maximum customization, but requires knowledge and care.
Maintenance: Replace coils when flavour drops off or tastes burnt. Keep wicking saturated to avoid dry hits. Clean tank components regularly.
Battery Safety
Devices with built-in batteries are the simplest - charge with the supplied cable and follow the manufacturer's guidance. For devices using replaceable 18650/21700 batteries:
- Use batteries from reputable manufacturers, purchased from a trusted retailer. We stock options like the Aspire 18650 and Hohm Tech cells - see our battery collection.
- Always carry spare batteries in a protective case, never loose.
- Inspect wraps regularly; do not use batteries with torn or damaged wrapping.
- Use an external charger designed for the battery type where the manufacturer recommends it.
- Understand Ohm's law before using unregulated devices - exceeding a battery's current rating can cause overheating.
Vaping Styles: MTL vs. DTL
- Mouth-to-lung (MTL): Draw vapour into the mouth first, then inhale - similar to the draw of a traditional cigarette. Tighter airflow, higher-resistance coils, higher nicotine strengths. Typical of pod systems.
- Direct-to-lung (DTL): Inhale vapour straight to the lungs. More open airflow, lower-resistance coils, denser vapour, lower nicotine strengths. Typical of sub-ohm tanks and mods.
Tuning Flavour and Vapour
- Airflow: A tighter draw generally intensifies flavour; more open airflow increases vapour volume.
- Wattage: Stay within the coil's recommended range (printed on the coil). Lower wattage can highlight subtle flavour notes; higher wattage increases warmth and vapour.
- Temperature control: Available on many regulated mods - sets a maximum coil temperature to reduce the chance of burnt hits.
- E-liquid choice: Higher PG blends tend to deliver more pronounced flavour; higher VG blends produce thicker clouds.
Troubleshooting
- Leaking: Check seals and O-rings, avoid overfilling, and match the e-liquid ratio to your coil type.
- Burnt taste: Replace the coil, check that wicking is saturated, and consider lowering wattage or enabling temperature control.
- Weak vapour: Check battery charge, clean airflow paths, and confirm wattage is within the coil's range.
