I've found that with nicotine it is much easier for me to stay alert and focused. It sometimes can wake me up, similar to caffiene, but also calms me at the same time. I generally get higher scores on standardized tests after consuming nicotine than I would without nicotine. Without nicotine my thoughts are often overactive and jumbled, similar to trying to have multiple conversations with multiple people at once. I often think on 2-3 tracks at a time, and sometimes as much as 4 or 5 if I'm feeling particularly perky that day. Caffiene worsens this condition as it allows me to think more efficiently and therefore concentrate on more things at once. Nicotine helps me eliminate all of the excess chatter and focus on 1 or 2 topics at a time.
I've also found it to relieve stress and prevent oncoming stress from building. I also have fairly low blood pressure (sometimes when I stand up too quickly I will become light-headed, or if I try to quickly begin rigourous activity I find I need to sort of psych myself up first). Nicotine seems to level this out as well, (I think by raising my blood pressure slightly), and while on nicotine I no longer experience either of the previously mentioned effects. It also prevents minor muscle spasms (shaky hands or eyes). I find it easier to focus my eyes, and in turn, easier to read, especially while reading small text even though I have better than average vision.
Can anyone else relate to any of these benefits or possibly add some?
Reading your post reminds me of the dozens of cannabis users that have told me how it's safe, makes them more alert, helps them to focus and lots of other 'benefits' that it brings. It's only when they have been off the stuff for a few years that they realise what a load of crap they were talking and how it was all drug induced justification to carry on using the drug.
I agree that nicotine irritates the nervous system and keeps it awake, but healthier living, exercise and good sleep does it better. The problem with any enhancing drug is that whatever benefits it may bring there is always a price to pay, whether it's dependency, physical deterioration or the pain of withdrawal.
I would like to see a controlled test in which users of e-cigs did not know whether or not the cartridges they were smoking contained nicotine. I won't be so foolish as to predict results but I will look for local volunteers for an informal experiment.
