I believe they are. E-cig companies are making claims that they are smoking alternatives that are close enough to the real thing, or that they are smoking cessation devices. I believe both claims are questionable. A study in New Zealand showed that the e-cig worked no better than the patch. I've experimented with vaping for a few months. I was never interested in quitting, merely for looking for a way to "smoke" in an apartment that doesn't allow it. However, I'm finding they aren't as satisfying to vape as smoking a real cigarette. If I had known about these issues before I dived into the world of vaping, I might not have bothered. What do you think? Why do so many people on these forums struggle to adjust to e-cigs?
