An e-cigarette is a type of vaporizer that combines nicotine and a flavoring agent. The nicotine content can be expressed as mg/mL or as a percentage (% v/v). There are several different flavors, each with a different amount of nicotine.

Tobacco-flavored e-cigarettes are the most popular and are preferred by smokers who have just started vaping. Non-tobacco-flavored e-cigarettes contain flavors that are not tobacco-flavored, such as spice or mint.

Studies have shown that some e-cigarette flavourings can be toxic to human cells. The most toxic flavouring chemicals are CAD, O-vanillin, and pentanedione. However, other flavours do not appear to be toxic at the concentrations tested. In addition, acetoin, diacetyl, maltol, and coumarin did not show toxicity in human cells.

Tobacco e-cigarettes reviews say they are not an effective substitute for smoking. Smokers should only use these products as a last resort to quit smoking. While many smokers who use e-cigarettes have quit smoking altogether or drastically reduced their cigarette intake, e-cigarettes do not provide a cure-all solution. The FDA has strict regulations concerning e-cigarette marketing and prohibits the manufacturers from labeling them as a quit smoking aid.

Vape pods are one of the most recent options available. These two-piece devices contain a battery and an atomizer. Some pods have only a few flavors, and others are refillable. The battery on e-cigarettes is rechargeable via a USB power adapter. Regardless of how you choose to use it, you will want to make sure you have a charger handy.

As has been doscvered by many researchers e-liquid flavors of e-cigarettes are gaining popularity among young adults. Studies show that youth are more likely to report using fruit-flavored e-cigarettes than adults. However, menthol and mint-flavored e-cigarettes are less common among these groups. Youth in Texas and Connecticut reported using flavor-flavored e-cigarettes than did their older counterparts.

Nicotine concentration and the level of menthol in an e-cigarette's solution have a significant effect on the appeal of the vapor. High-menthol concentrations were perceived as "cooler" than other flavors by smokers. This coolness factor is positively associated with appeal. The sweetness of a vape was also positively influenced by menthol content.
