The less popular nicotine replacement therapies tend to be the nicotine inhalers and the nose spray, and they may be less popular simply because they require a doctor's prescription, which can be pretty annoying for many of you who up and decide to quit overnight and don't have the time to make a doctor's appointment. The inhaler (sometimes called the "puffer") works sort of like an asthma inhaler -- you stick it to your mouth and release a small burst of nicotine whenever you have a craving. Most inhalers have around 400 puffs in them, which delivers around the equivalent of six cigarettes, so you may go through quite a few inhalers in a week's time. Some of the inhalers, also, are easy to carry around and even hold/twirl in your hands, which might relieve some of your hand fixation issues -- it can sort of mimic the act of smoking a cigarette (in fact, I've seen people who simply chew on the inhalers in between puffs). I have to be honest, I've not tried the inhaler for any extended period of time -- I've borrowed one or two from friends, and they seem to work okay, but if you're using 6 - 16 cartridges a day, plus the doctor's bill, I can image it would run into quite an expense.
Likewise, I've never even tried the nicotine nasal spray, and quite honestly, I have no desire to do so. Snorting droplets a nicotine through my nostrils simply doesn't have a lot of appeal, especially in public places, though I do imagine that the nicotine is delivered into your bloodstream quickly, because it travels through the nasal membranes (which is why people snort cocaine). However, it might be inconvenient to stick a nasal spray bottle up your nostril twice an hour, which is what is recommended. Moreover, from what I understand, the side effects include nasal irritation, a fast heart rate, and diarrhea, which I'm not okay with. Plus, it has the same hang-ups that the inhaler does, in that you have to get a prescription to use it.
