I really want to know how safe this thing is! I know nicotine can be dangerous in large doses (well not really large but overdose is common).
Children go to hospitals if they chew a cigarette and when a user has the liberty to pour liquid nicotine in a cartridge without proper regulation, I wonder how safe it is.
Luckily, I have not heard anyone post serious health problems other than headaches and nausea.
If you have OD using the electric cigarette, post your story. Please!
