The “study has demonstrated for the first time that nicotine restores dynamic intrinsic brain activity in the left DLPFC in patients with schizophrenia,” the researchers conclude. “This interaction may be a clinical neuromarker for increased comorbid smoking in schizophrenia.”
Probably because its a depressant. Perhaps chewing real tobacco leaves has a place in medicine (not recrationally) but cigarettes and inhaling smoke. No. Modern cigarettes are also laced with cancer causing chemicals
I get my nicotine through vaping. I wonder what would happen if I stopped ?
Also how long does this effect last? My guess is for a short term (the length of a short study?) but declines more with longterm use which…is essentially what we experience…short term relaxation which then longterm fades away and becomes a harmful addiction
You would hallucinate and your anxiety would shoot up.
Speaking from personal experience.
I suspect anything too far from its natural state would lead to intemperate use, not to mention the heath effects of the additives, leading to greater sadness
i am stopping smoking now
I’m not gonna start a new addiction, but I wonder if nicotine patches could have a place in medicine other than for quitting smoking.
I am more productive when I not smoke , it’s just a delusion that smoking helps
I have to admit, I like tobacco.
I might quit smoking and get the patches.
Either good or bad, tobacco dominates the globe. 
Actually cigs are a stimulant
Its actually both a stimulant and depressant lol.
Where’s it say that at? Nicotine I always thought was a stimulant and that’s it
No I get what your saying in low doses it can be a depressant but for the most part higher doses are a stimulant’s which is like one cig
You got it on point. Low doses = depressant, high doses = stimulant.
