Actually, this is incorrect. Ok, it's partially correct.Miles Tormani said:It relieves stress. It also calms your nerves. Your hands are actually steadier if you smoke a cigarette beforehand.
Also, it's legal. Holy shit, right?
Nicotine is an agonist of the nicotinic acetylcoline neuroreceptors, in other words, it's a sort of stimulant. It's a dependency-inducing stimulant (like most drugs). The principles of pharmacokinetics and pharmacodynamics will tell you, in short, that the more you abuse a substance, the more you'll face the exact opposite effects when you're not on said substance. As it's regularly known: withdrawal symptoms.
So basically, without going too much into the exact effects of nicotine as a neurotransmiter, there are 2 effects at work here:
1 - Nicotine as a muscular stimulant may help you regain muscular control if tired, due to an activation of the sympathetic nervous system (i.e.: "Fight or flight" response).
2 - A regular smoker will experience the exact opposite effects on a regular basis while not under effect of the nicotine, so their tendency to have their hands shake at all, feel more stressed, more tired, and such will be much higher, which will be "normalized" upon the next administration of the drug at hand (nicotine).
In shorter words: it's not that smokes make you all that calmer or all that more "stable", they just fuck you up more when you're not on them so you think they're making you better.
