What are the best cigarette flavors?

E-liquid vendors are becoming more common in The United States as consumers push for American made varieties. Hundreds of different flavor varieties are available. Some attempt to resemble traditional cigarette types, such as regular tobacco and menthol, and some even claim to mimic specific cigarette brands, such as Marlboro or Camel. A wide variety of food flavors are also sold, from the traditional (vanilla, coffee, cola) to the more exotic (strawberry daiquiri, Boston cream pie).

Nicotine:

Liquid solutions containing nicotine are available in differing nicotine concentrations to suit user preference. Dosing nomenclatures are not standardized and vary by manufacturer, but tend towards the following rough figures: Liquids said to contain "low" doses of nicotine tend to correspond to a nicotine concentration of between 6 - 9  mg/ml (milligrams of nicotine per milliliter of liquid)."Midrange" or "medium" doses tend to correspond to a nicotine concentration of 10–17 mg/ml."High" doses tend to correspond to a nicotine concentration of aprox 18–22 mg/ml."Extra-high" doses tend to correspond to a nicotine concentration of 24–36 mg/ml.Actual numerical nicotine concentration ratings are usually printed on liquid containers or cartridge packaging. Often, the standard notation "mg/ml" is shortened to a simple "mg". Nicotine-free solutions are also a widely offered option.

Bases:

Flavors and nicotine are dissolved in hygroscopic components, which turn the water in the solution into a smoke-like vapor when heated. Commonly used hygroscopic components include propylene glycol, vegetable glycerin, and polyethylene glycol 400 (often sold under the abbreviations PG, VG, and PEG 400, respectively).

Safety of liquid bases

All three liquid bases are common food additives used in a variety of pharmaceutical formulations. Propylene glycol, the current dominating liquid base, has been utilized in asthma inhalers and nebulizers since the 1950s, and because of its water-retaining properties, is the compound of choice for delivering atomized medication. The U.S. Food and Drug Administration (FDA) includes propylene glycol on its list of substances Generally Recognized as Safe (GRAS), and it meets the requirements of acceptable compounds within.

Title 21 of the Code of Federal Regulations. In comparison, traditional tobacco cigarettes contain at least 80 cancer causing chemicals, including tar.

Propylene Glycol:

Propylene Glycol is a colorless, nearly odorless, syrupy liquid that is derived from natural gas. Because it comes in different grades, PG is used in a variety of things from engine coolants and airplane de-icers to hand sanitizers and deodorant sticks. Although there is much controversy over this substance, both the FDA and the World Health Organization have deemed the pharmaceutical grade of propylene glycol safe. Disadvantages/Hazards/Risks.

The health effects of using electronic cigarettes are currently unknown. Several studies regarding the long-term health effects of nicotine vapor, both inhaled directly and second hand, are currently in progress, although it should be noted that second hand side stream smoke is non-existent due to on-demand operation and that vapor is generated rather than smoke.

Health Canada:

On 27 March 2009, Health Canada issued an advisory against electronic cigarettes. The advisory stated "Although these electronic smoking products may be marketed as a safer alternative to conventional tobacco products and, in some cases, as an aid to quitting smoking, electronic smoking products may pose risks such as nicotine poisoning and addiction.
