I think this is a really good idea for a thread. I haven't gone through and read any of the posts yet, but I wouldn't doubt it if more people posted about good effects than bad ones even though it's specifically about bad effects. I've personally been so much better since I started vaping. I ended up having to quit due to a serious medical condition. Since then I've been so much better though. I did have a bad experience though (a few of them).
I ordered some e-liquid from a website (can't name names, so I'm gonna say that it was a custom e-liquid supplier) and it made me really sick. At first I didn't think it was the e-liquid that was causing the problem, but it happened a few times, so I'm sure it was the cause. When I would vape the stuff I would get a funny feeling in my head almost immediately and after a few drags I couldn't vape it anymore. Then within 5 minutes I would get so nauseous I'd have to lay down. It was pretty intense. I also noticed that my heart rate would go down really low after vaping it too. Before I realized it was the e-liquid a friend of mine tried it (a non e-cig user) and he said it made him feel funny in his head. He said that he felt like his soul was bigger than his body like it was so big it didn't fit. The way he described it was that it was like a partial out of body experience. Then a few minutes after that he said that the top of his head and his forehead went numb and tingle, which also happened to me.
The place I ordered from has tons of satisfied customers and I'ver never heard of anything like this happening to any of their customers or anyone else for that matter. I know some people are going to take things people put in here as evidence that e-cigs are bad, but I still think they're a blessing. I think e-cigs are one of the best investments I've ever made in my life. Also, I just wanted to add that I got a different kind of e-liquid (cinnamon)from the same supplier and it was great and even though I had them problems I still ordered more e-liquid from them the other day. I can't wait to get it.
If anyone's worried about e-cigs not being safe because of a few problems people are having just remember how many people that smoke analogs have problems from them. ALL OF THEM. Every person in the world that smokes regular cigarettes has problems from them. It's like airplanes. There's crashes here and there, but it's still the safest way to travel by far.
