For most people switching from cigarettes, taste and smell get noticeably better. Vapers do sometimes experience a different short-term issue called vaper's tongue, but that is usually easy to fix.
The good news first. Cigarette smoke damages taste buds and dulls the olfactory nerves that handle smell. Long-term smokers have measurably lower taste sensitivity than non-smokers, particularly for salt, sweet, sour and bitter.
A 2017 study using electrogustometry confirmed that taste sensitivity recovers fairly quickly after you stop smoking. Most people notice food tasting more vivid within 2 to 4 weeks of switching, and coffee, fruit and fresh bread often smell stronger almost straight away.
A lot of customers tell us coffee was the first thing that hit them. A few days after quitting cigarettes, the morning brew suddenly smelled the way it used to.
If you still smoke alongside vaping (dual use), taste recovery will be slower. The benefit really shows up once cigarettes are out of the picture entirely.
This is the term for suddenly not being able to taste your e-liquid properly. The flavour goes flat or disappears altogether, often despite the device working fine.
It is usually temporary and almost never a sign of anything serious. Most cases last between a few days and two weeks.
If your flavours have gone flat, one of these is almost always the reason.
01
Flavour fatigue
Your nose and taste buds adapt to scents and flavours they are constantly exposed to. Vape the same juice for weeks and your brain stops registering it properly.
02
Dehydration
Saliva is essential for taste. PG and VG in vape juice dry your mouth out, which directly reduces flavour perception.
03
Recently quit smoking
Your taste buds are still recovering. This can make new flavours feel inconsistent for a few weeks.
04
Cold, sinus issue or medication
Around 70% of what you taste is actually smell. A blocked nose or certain medications can knock both out at once.
Try these in roughly this order. Most people are sorted within a few days.
Drink more water
The simplest and most effective fix. Saliva is essential for taste. Aim for an extra 500ml beyond your usual.
Switch flavours for a few days
If you have been on the same juice for weeks, change to something different. Sweet to menthol, fruit to tobacco. Resets your palate.
Brush your tongue and use mouthwash
A coating builds up on the tongue that can dull taste. A proper tongue scrape or a tongue-cleaning toothbrush helps.
Smell coffee beans
An old sommelier's trick. Strong coffee smell resets your olfactory sense, which is most of taste perception.
Suck a lemon or eat something sour
Stimulates saliva production and gives your taste buds something to react to.
Take a vaping break for 24 to 48 hours
If nothing else works, give your taste buds a full reset. Use a nicotine patch or gum to manage cravings if needed.
A few myths come up in vape forums that are worth flagging.
Vaper's tongue is a vape-flavour issue. If your sense of taste or smell goes for real food and everyday smells, that is different and worth getting checked. Contact your GP or use NHS 111 if any of these apply:
Switching from cigarettes improves taste and smell
For most former smokers, the senses come back noticeably within 2 to 4 weeks. Coffee, fruit and fresh bread are usually the first wins.
Vaper's tongue is temporary
It is almost always flavour fatigue, dehydration or both. Most cases sort themselves within a few days of trying the fixes above.
Real loss of senses is worth a GP visit
If everyday food and smells become dull or vanish for more than a few weeks, that is different and needs proper attention.
