Switching from smoking to vaping can be life-changing, especially for heavy smokers seeking a cleaner, more customisable alternative to cigarettes. One of the first – and most important – decisions you will face is choosing the right e-liquid strength and type. For those who smoke a pack or more per day, understanding the difference between freebase nicotine and nicotine salts (nic salts) is critical for achieving satisfaction, minimising cravings, and avoiding relapse.
In this guide, we will explore how freebase and nic salt e-liquids differ, what strengths are best for heavy smokers, and how to make the switch with confidence.
Understanding Nicotine In E-Liquids
Nicotine is the addictive compound in tobacco and also the key ingredient in e-liquids that provides the “throat hit” and satisfaction smokers crave. In vaping, nicotine comes in two main forms, namely freebase nicotine and nicotine salts.
Freebase Nicotine
Freebase nicotine is the traditional form used in most standard e-liquids and has been around since the early days of vaping. It is created by stripping nicotine from its natural salts and converting it into its purest, most potent form.
Key Features Of Freebase Nicotine
- Provides a stronger throat hit at higher concentrations
- Best suited to lower-strength formulations (typically up to 18 mg)
- Commonly used in vape juice for sub-ohm devices
- Slower to absorb into the bloodstream compared to nic salts
Nicotine Salts (Nic Salts)
Nicotine salts are a more recent innovation. These e-liquids contain nicotine in its natural state, combined with an acid (like benzoic acid) to lower the pH level, making the experience smoother even at higher strengths.
Key Features Of Nicotine Salts
- Allows for high nicotine concentrations (20 mg – 50 mg) without harshness
- Smooth inhale with minimal throat irritation
- Absorbed more quickly into the bloodstream, mimicking the rapid nicotine hit from cigarettes
- Ideal for low-wattage pod systems and MTL (mouth-to-lung) devices
Which Is Better For Heavy Smokers: Freebase Or Nic Salt?
The answer to this question depends greatly on your nicotine dependency, vaping style, and device choice.
Nic Salt E-Liquids: Best For Quick Satisfaction
For most heavy smokers transitioning to vaping, nic salts are the preferred option – especially in the first few weeks of quitting cigarettes.
Why?
- Higher nicotine levels (typically 20 mg or more) closely match the nicotine delivery of cigarettes
- The smooth throat hit reduces coughing or irritation often caused by stronger freebase e-liquids
- Faster nicotine absorption offers quicker relief from cravings, mimicking the immediacy of a cigarette
Nic salt e-liquids pair well with compact pod systems or low-power MTL devices, making them ideal for beginners. These setups are discreet, user-friendly, and provide a draw similar to smoking.
Freebase E-Liquids: Better For Throat Hit & Cloud Production
Once a smoker has adjusted to vaping and begins lowering nicotine intake, freebase nicotine may become more appealing.
Heavy smokers who enjoy the sensation of a throat hit may prefer a stronger-feeling vape, even if it delivers less nicotine. Freebase liquids in the 12 mg – 18 mg range can satisfy cravings while offering more control over vapour production and flavour complexity.
These liquids are best suited for higher-wattage vape kits or devices with variable airflow, giving users more flexibility and performance.
E-Liquid Strength Recommendations For Heavy Smokers
Now that we have covered the types of nicotine, let us match them to practical usage for heavy smokers:
Cigarettes Per Day | Nic Salt Strength | Freebase Strength | Best Option |
15 – 20 cigarettes | 18 – 20 mg | 12 – 18 mg | Nic salts |
20+ cigarettes | 20 mg (or higher) | 18 mg (may be harsh for some) | Nic salts strongly recommended |
Chain smokers / dual users | 20 – 36 mg | Not ideal due to harshness | Nic salts with higher strengths |
Device Compatibility: A Key Factor
Heavy smokers must also consider device compatibility when choosing an e-liquid type.
- Freebase nicotine is best used in sub-ohm tanks or box mods operating at higher wattages (20 – 80 W+). These devices produce larger vapour clouds and more intense throat hits, but they also consume more e-liquid.
- Nicotine salts shine in low-wattage pod systems (typically 10 – 20W), which are simpler to use, leak-resistant, and great for discreet vaping.
Choosing the wrong type of e-liquid for your device can result in harsh hits, poor vapour production, or even coil burnout, so it is essential to match e-liquid and device type properly.
Freebase Vs. Nic Salts: Pros And Cons
Feature | Freebase Nicotine | Nic Salts |
Throat hit | Strong at high strengths | Smooth even at high strengths |
Nicotine absorption | Slower | Faster (more cigarette-like) |
Suitable strength for heavy smokers | 12 – 18 mg (can be harsh for some) | 18 mg+ |
Ideal device | Sub ohm – higher wattage | Pod systems – lower wattage |
Flavour clarity | Typically better | Slightly muted due to acid contents |
Flexibility for reducing nicotine intake | High | Lower (less common in low strengths) |
Transition Tips For Heavy Smokers
Switching to vaping is not just about buying a vape and puffing away – it is a process. Here are some tried-and-tested tips to help heavy smokers make the switch successfully.
Start With Nic Salts
For the first 1–3 weeks, use nic salts in the 18 – 20 mg range (or higher in the U.S.) to satisfy strong cravings. This provides a smoother experience and curbs the desire for cigarettes faster.
Use A Pod System First
Devices like refillable pod kits or closed pod systems are simple, portable, and mimic the draw of a cigarette. These are ideal for heavy smokers easing into the vape world.
Vape Consistently
Do not wait until cravings become unbearable. Take a few puffs every hour or so to keep nicotine levels steady, especially during the first week.
Experiment Gradually
Once you are comfortable, try reducing nicotine strength or exploring freebase options. Transition to a sub-ohm kit if you enjoy cloud production or want more control.
Stay Hydrated
Vaping (especially with higher nicotine) can be dehydrating. Drink plenty of water to avoid dry mouth, headaches, or fatigue.
For heavy smokers, nicotine salts are the go-to option when first transitioning to vaping. They offer the satisfaction, strength, and smoothness needed to replace smoking effectively. Once cravings lessen, you can explore lower nicotine levels or shift to freebase e-liquids if you prefer a stronger throat hit or more intense flavours.
The most important thing is to find what works for your body and preferences. Vaping is a flexible and personalised experience, so do not be afraid to experiment until you land on the perfect combination.
Ready to make the switch? Choose quality e-liquids, use a suitable device, and give your body a few weeks to adjust. With the right setup, even the heaviest smokers can finally say goodbye to cigarettes for good.
