Choosing e-liquid as a heavy smoker: strength, kit and flavour

A common story: a heavy smoker tries a low strength liquid in a big cloudy kit, finds it unsatisfying, and goes back to cigarettes. The problem was almost never vaping itself. It was the wrong strength, the wrong kit, or both.

Cigarettes deliver a quick hit with a tight draw. To get close to that, you need enough nicotine in the liquid and a device that draws like a cigarette. Nicotine is addictive, and the goal here is simply to find a setup that is satisfying enough that you are not tempted back to smoking. The NHS says nicotine vaping is less harmful than smoking, though it is not risk-free and is for adults who smoke, not for non-smokers.

For heavier smokers, the two usual starting points are 20mg nic salt and 18mg freebase. Salts feel smoother, so 20mg is comfortable even for people who find freebase harsh. Freebase at 18mg gives a firmer throat catch that some smokers actively miss.

If you feel dizzy, lightheaded or sick, you are taking in more nicotine than you are used to, so step down or slow down. If you find yourself puffing constantly and still craving a cigarette, your strength may be too low. Both are fixed with a different bottle, not by giving up. Shop strengths in the nic salt range.

A tight mouth-to-lung (MTL) draw is the closest feel to a cigarette. Look for a pod or pen kit with a coil of around 0.8 to 1.2 ohm and adjustable airflow you can close down. Kits such as the Innokin Endura T18E or Uwell Caliburn G3 Lite are built for this kind of vaping.

Avoid big sub-ohm tanks to begin with. They produce huge clouds, need low strength liquid and feel nothing like a cigarette. A bigger battery is a bonus, because a heavy smoker tends to vape a lot and a flat kit at 4pm is a real risk to your plans.

Pick the description that matches you best. These are starting points drawn from years of helping customers, not rules, and you can fine-tune strength after a week or two once you know how you vape.

Plan on getting through more liquid than you expect in the early weeks, because many people puff more while they get used to vaping. A few 10ml bottles in two or three flavours is a sensible first order. Keep a backup coil or pod too, so a burnt coil does not leave you without your vape at a bad moment.

Many smokers start with tobacco flavours because they feel familiar, and menthol is the obvious choice for anyone who smoked menthols before the UK's 2020 ban. Plenty of people then drift to fruit or dessert flavours after a few weeks, finding that tobacco flavours remind them of cigarettes a bit too much.

There is no wrong answer. Buy two or three different styles at the start, such as a tobacco, a menthol and a fruit, and rotate them. Rotation keeps flavours vivid, and having options means you are less likely to get bored and give up on the vape.

A smoker on about 25 a day buys a sub-ohm tank kit, fills it with a 3mg shortfill on a friend's recommendation and finds it pleasant but unsatisfying. They are back to buying cigarettes within a week and feel like vaping simply is not for them.

What would most likely have made the difference? Pick the change that addresses the real cause rather than the symptom. Think back to what a cigarette actually feels like to draw on, and how much nicotine a heavy smoker is used to, then compare that with what the tank and the 3mg liquid were offering. The gap between those two things is where the answer sits.
