Your question seems to be predicated on the idea that there is something wrong or bad about vaping nicotine and that it is desirable to cut back. Examine that perception first.
A wisdom has been shared is that you should increase your nicotine dose. Though contrary to your intuition, it will increase your satisfaction and reduce your tendency to chain vape. Ensuring you are satisfied is of utmost priority, since this is what stops you from reverting to cigarettes.
A foolishness has also been shared: that you should exercise more self-control. This is hypocrisy itself since the proponent betrays his own lack of self control through his dependence on vaping. However, self-control is a laudable quality and one that we should all strive for. Perhaps this goal can be deferred.
Is there anything wrong or bad about vaping nicotine? There certainly are a lot of people and entities claiming so. Your own government health department probably says so. Your own family and friends probably share their doubts. But does not the harm in tobacco originate in combustion? There is no combustion in vaping.
Nicotine itself is not carcinogenic, nor does it cause a debilitating addiction. It unquestionably does cause a chemical dependence—wherein your body becomes accustomed to it, demands a regular supply, and rebels when deprived. However, many have found that this dependence no more debilitating than a dependence on caffeine.
Is there harm in the vapor? A
recent study by the American Center for Disease Control showed that in a typical vape lounge, toxic emissions were below occupational exposure limits across the board. So harm in vapor seems unlikely.
Perhaps then, if there is no harm in vaping nicotine, this is a habit you should take pride in and embrace wholeheartedly. Wouldn't it feel good to exorcise that demon of self-doubt? What if, instead each puff being a guilty pleasure, each puff could be a minor victory and a pat on the back? That's certainly the way I'd prefer live. How about you?
