Hi i'm not sure if this is in time but i think u need to correct some information. The below blue fonts are abstracts from ur article. Can be found on page 3 and 4.
Electronic cigarettes are only supposed to contain four different ingredients. These four ingredients are water, propylene glycol, nicotine, and flavorings. (Propylene Glycol). Propylene glycol is used in electronic cigarettes to provide that thick vapor.
I think you forgot about VG. Vegetable Glycerin. It is use to provide the thick vapor as well. Works as diluants like PG and is a 'natural extract' (but we all know Vg dun carry the flavor as good as PG but is irrelevant here. You can also include "Pure grain alcohol is used sometimes as a diluant to flavorings" which i don't think u need to lol.)
Water would actually be too general. It should be distilled water. Tap water contains too many chemical that makes it unsafe for vaping or rather, not proven to be safe yet.
If you do a research on nicotine, it’s hard to find information regarding nicotine by itself. Nicotine is almost always accompanied by other information such as why cigarettes and tobacco are bad for you.
Actually nicotine is found on tobacco leaves hence the relation but u can find info about nicotine itself on the web quite easily, being a poison at higher lvls etc etc (ur point of 'hard to find info on nic itself' is not entirely valid)
Smoking not only effects those of you that smoke, it also affects the people around you while smoking. It also affects the people that have to smell the smoke on you all day at work or school.
I think u can enhance this point by adding what is known as "third hand smoke" When smokers are done with, particles from the burnt tobacco often clings on to the clothing, hair and whatnot of the smokers. These particles are generally known as 'free radicals'. There r studies out there showing how 'third hand smoke' can actually affect another's health. i.e. a smoker father after finishing his stick OUTSIDE the house (to keep family members away from 2nd hand smoke thinking its safer for them), proceeds indoor and carry his newborn. The newborn thus inhale the free radicals from his father's clothing or hair etc.

Also, gums are chewed. and patches are, well, pasted onto the skin of the users. They both works similarly, due to the fact that nicotine is dermal (will get absorb into bloodstream from surface of skin), gums when chewed will released the nicotine into ur bloodstream via ur gums and of cuz tooth cavities (which isn't pleasant at all cuz it hurts like shlt! and not to mention the awful taste of it =.=) and patches which doesn't require one to do anything except pasting it. Both of these releases nicotine into ur body for the nicotine fix but neither of these provide the simulation to the actual smoking itself. From the picking up and putting to lips, to the inhaling and exhaling of smoke And the feeling of smoke going into lungs and out thru the throat and nasal~. This is one of the reason why some smokers turn to food and snacks whilst quitting due to the body wanting to have the feeling of "ingesting". (which of cuz u have already mentioned most of the point here in ur article)
Other than the points i mentioned, the rest of the article are more or less a thumbs up except for grammatical errors and sentence structuring, which u might wanna look through again.
Good luck!! vape on~
