An e-cigarette liquid is made up of: propylene glycol, Vegetable Glycerin, flavourings, nicotine or not. The flavourings may contain a little water or alcohol as a diluent.

In France, all e-liquids containing nicotine must be declared to the government (ANSES) 6 months before being marketed, with the full list of ingredients in the recipe and the list of molecules emitted during vaping. The government knows exactly what each nicotine-containing liquid contains, and what it emits.

No, nicotine is not at all carcinogenic; it's the burning of tobacco that is. Nicotine is not toxic to the body except in very high doses.

Nicotine has a similar effect to caffeine. Do you try to lower your caffeine dose every morning?
There's no particular need to lower your nicotine strength.
However, if you want to kick your nicotine addiction, it's a very good idea to reduce your nicotine strength very slowly and regularly (every 3-4 months at least, no faster, otherwise you'll go back to smoking).

There are two possible causes: either a clogged or broken coil that you simply need to replace to get the flavour back, or a taste habit that can cause a loss of flavour, in which case you simply need to change e-liquid.

The nicotine in the e-liquid, when it oxidises, gives the e-liquid a darker colour. There's nothing to worry about, so it's normal for the colour of the e-liquid to darken over time.

To store an e-liquid, it is essential to avoid direct sunlight and excessive heat, which degrade nicotine and flavour. A simple storage cabinet will suffice.

You can mix two liquids of the same flavour with different nicotine strength without any problems. For example, mixing a 3 mg/ml and 6 mg/ml nicotine liquid will give you 4.5 mg/ml.

However, we strongly advise against mixing e-liquids with different flavours, as some flavours react with each other and can produce potentially undesirable and harmful molecules.

The BBF/DDM is the best before date for your e-liquid. This means that after this date, the e-liquid is not unfit for consumption, but its qualities are not optimal. If the date is exceeded by one or two months, you won't be taking any risks. On the other hand, e-liquid with a best-before date older than 6 months or that has changed colour (turned black) should not be vaped, as there is a risk that the flavours will be too degraded.

First of all, you need to check the maximum usable VG content on your equipment's product sheet. If your equipment does not appear on our site, please contact us. In short, for an e-liquid with a VG rate > 50%, your coil should have wide opening holes. Once the percentage of VG has been determined, all you have to do is choose your liquid according to your tastes. If in doubt, we'll be happy to advise you.

Calumette only offers quality brands. So you can choose any brand you like.

We advise you to choose a VG/PG ratio of around 30/70 to 50/50. The VG content should not exceed 50% to start with, and you need to do an indirect inhalation.

Test several styles of e-cigarette e-liquid to find the one that suits you best: at least one flavour oriented towards Classic blond or Classic brown, a mint or ice mint or fresh mint or menthol e-liquid, a fruit e-liquid such as red fruits or raspberry or blueberry or liquorice or aniseed or caramel or vanilla. At first you'll probably take Classic flavour e-liquid, then you'll discover that with a gourmand flavour, you can reach the grail of vaping. If you're in the process of giving up smoking and switching to vaping, it's important to try several eliquids so that you don't give up on the first one if it doesn't suit you. Avoid mixing different flavours, which can generate toxic or dangerous molecules.

An e-liquid can make you cough at the start of vaping, this is very common. The nicotine contained in an e-liquid has no additives to soften its slightly irritating side, and when you're a former smoker your airways and larynx are often very irritated, which amplifies the phenomenon. All you need to do is vaporise slowly and break down the inhalation well for the phenomenon to disappear. If irritation prevents you from vaping the right strength of nicotine at first, you can also switch to nicotine salts, which, because they don't hit, allow you to vape high strength of nicotine without discomfort. You can also try an e-liquid with Vegetol, which contains no PG and is less irritating.

If the phenomenon doesn't go away, it's because your equipment isn't suitable (direct inhalation should be avoided if you cough) or because you're allergic to one of the components in the liquid. Don't think that all irritations are due to PG. It can come from the flavourings but also from the VG. You'll need to test several different brands of e-liquid to find the right one.

Sometimes when you first start vaping, your body isn't used to the slower release of nicotine, so you vape continuously, which can cause dizziness or headaches. All you need to do is lower your nicotine strength or vape less. This is generally a very temporary phenomenon.

The good thing is that as soon as you start to overdose on nicotine, your body lets you know straight away!

Because nicotine diffuses more slowly through the body. It's perfectly normal to have a lot of vaping during the first few weeks, while your body gets used to it. This phenomenon disappears fairly quickly, provided you have the right nicotine dosage (and not too low!).

These are e-liquids containing at least 80% VG. They are made for direct inhalation and produce large clouds, and require suitable equipment (large openings for liquid to enter the resistance). Not for beginners.
