Benefits of E-liquid for
smokers and non-smokers

2. No foul smell – The smoke produced by electronic
cigarettes does not release a bad smell on your clothes,
mouth and hair. Electronic cigarettes smell dimly and if you
use flavored electronic cigarettes, you won’t smell like
tobacco, you will instead smell of sweet flavor that you
have chosen. Electronic cigarette smell doesn’t irritate the
people around you.
Easy to fill up and use – Vapor smoke juice is very easy
to fill in the atomizer. Electronic cigarettes involve just
replacing a cartridge or filling it up with e liquid. It also
comes with instructions to make the whole process simple
.To fill the atomizer with e-liquid you drag off the
mouthpiece section of the atomizer to reach the chamber
where you will transfer your e-liquid. You then transfer the
e-liquid in the unfilled space of the sides of the coil cylinder
but makes sure you don’t fill extra e-liquid in atomizer.

3. Different flavors – E-liquids come with
different flavors. Various e-liquids have
nicotine and there are also a few e-liquids
that are available without nicotine. E-liquids
are also available in tobacco flavor but the
effects are totally different from tobacco used
in regular cigarettes. With E-liquids you have
a variety of different flavors to choose from.
No Nasty Toxins – E-liquids don’t contain
any toxins like regular cigarettes do which
means no tar, no hydrogen cyanide, no lead,
no arsenic and no carbon monoxide.
Tobacco cigarettes contain more than 4000
chemicals but there are no hidden
ingredients or chemicals in e-liquids. They
usually have 4-5 different ingredients.

4. Cheaper – E-cig liquid is cheaper than tobacco. E-liquid
satisfies you with one puff which is not the case with
tobacco cigarettes. E-liquid is not addicting like tobacco
cigarettes are. You can purchase e-liquid in small packages
and one ml of e-liquid contains approximately 35 to 40
drops that is enough to fill a normal e-cig tank. A 10ml
bottle is equal to 5 packs of tobacco cigarettes.
No yellow fingers - When you vape e-juice your fingers
are left very clean compared to the yellow brown nicotine
marks associated with tobacco smoking. If you blow the
cigarette smoke on a napkin it will be yellow but with vapor
it remains white.
