I live with two family members who are heavy smokers, one of them is 60+ and the other is in his 30's. I just wanted to know if E-Cigs work or if they have anything that can harm them, because I don't want to introduce them to this and accidentally kill them. I've been wondering if the blu-cig premium set is enough for 2 people because they are pretty expensive! I am only 12 and I am sick of seeing them smoke and want them to quit, but i'm not willing to go far like hiding or disposing their cigarettes because that's kinda f*cked up. So I am willing to introduce them to this product to help them quit! Also, if there is anything better/cheaper than the blu-cig please do tell!
