What are the positives and negatives of e-cigs?

Pros: It is good to help stop smoking tobacco

One concern that has been raised that with the availability of e-cigs kids may be more likely to take up tobacco smoking. There are currently no laws regarding the age groups to which electronic cigarettes can be sold.

Positive: don't give off a smell, doesn't cause 2nd hand smoking, vapor
Negatives: Still has nicotine, as bad as a cigg

Ibelieve the answers are a and c.

Hepatitus b, hepatitus c, hiv, and tetanus
