I think the visibility of vapor is greater because the particle size is larger. So, on an equal size of inhale and exhale as one would do for a cigarette, the edges of the cloud that would be invisible with smoke are visible with the vapor. Also, as vapor is less of an irritant than smoke, some vapers take much larger drags from a vaporizer than they would from a cigarette. More in, more out.
I don't think it feels the same. There is less of a burn in the back of the throat, which is referred to as throat hit. Unfortunately, I rather like that burning feeling in the back of my throat, so I tend to use liquids with a lot of menthol. Actually, cranking up the nicotine also helps with the throat hit. I guess a comparison might be like the difference between light cigarettes and normal cigarettes. Some people, like me, just prefer the harshness of the normal cigarettes. The harshest vape I've had is still nothing compared to a "heavy" or handrolled cigarette.
I've just had a look at the Singapore story. They are also banning nicotine patches, chewing tobacco, snuff, and anything else that delivers nicotine but is not a cigarette, looks like. They said it was about keeping the number of nicotine consumers down in general, by eliminating the emerging market for nicotine products. If they were doing away with the actual cigarettes as well, I wouldn't think they were full of it.
If you surveyed Indonesians I'm sure most of them would tell you that vaping is more harmful than smoking. There was a very visible series of stories on the news a while back, quoting discredited studies. Can't say I'm impressed. Someone mentioned a sky news story they saw recently. I was just looking at one from the Telegraph... headline is "Vaping
As Bad For The Heart As Smoking..." Open it and the first line is "vaping
could be as bad as smoking for the heart, research
suggests CRYSTAL PRO MAX 4004." Click bait headline anyone? If you read through the whole of the article, it is disclosed that nicotine, the chemical we smokers/nicotine vapers are all addicted to... drumroll... is not good for the heart! What a revelation! The article also mentions that caffeine has a similar effect. No mention is made of the many carcinogens contained in cigarette smoke that are absent in vapor. No mention is made of the harmful effects that inhaling tar has upon the lungs.
When people treat such "news" as useful or insightful, I assume that they either: A, Are so vehemently opposed to smoking/nicotine consumption that they are also opposed to any "half measures" which people might use to reduce harm, B, Have a personal interest in preserving the status quo for tobacco companies, C, Of the type that can't/won't be bothered to understand what particular bit of gossip they are passing along, just so long as it might be of interest to someone. Thoroughly unimpressive.
