Caffeine

Caffeine is a drug that an overwhelming majority of Americans are going about their daily lives under the effect of right now. It alters the brain's natural state, and stimulates it in a manner similar to amphetamines such as cocaine or heroin. Its effects are much milder, of course, but

it's the same mechanism.

-It is absorbed quickly into the lining of the stomach and small intestine.

-It blocks adenosine receptors in your brain. Adenosine causes drowsiness, so cells that would normaly be regulated to slow down by way of adenosine actually speed up now.

-Your Pituitary gland sees the cells not slowing down and assumes there is some sort of emergency happening, and it releases hormones into your bloodstream telling your adrenal glands to start pumping.

-Your pupils dilate.

-Your blood pressure rises.

-Your liver releases sugar into the blood stream for extra energy.

-Your hands may get cold.

-Your smooth muscles relax. (Bronchial muscle is smooth muscle. Which is why asthma sufferers are sometimes given caffeine.)

-It takes about 45-60 minutes for it to reach peak levels in your bloodstream.

-Your dopamine re-uptake is inhibited (this is how it's like cocaine or heroin), and the pleasure centers of your brain are abnormally stimulated.

-Your reaction time to visual and auditory stimuli slows.

-The half-life of caffeine in your system varies depending on the state your body is in.

  • Smoker: 3 Hours
  • Average Human: 5-7 Hours
  • Pregnant Woman:18-20 Hours
  • Newborn Baby: 30 Hours

-Caffeine withdrawal symptoms include headaches that do not respond to pain killers, lethargy, confusion or inability to focus and irritability.

-75% of Americans Drink coffee regularly.

-90% of Americans daily consume caffeine in some significant (100+ mg) form.

-More than half of those consume more than 300mg daily.

-Mild caffeine overdose (750+ mg or about 7 cups of coffee) of caffeine can lead to dizziness, visual hallucinations (flashes), delirium, diarrhea and fainting.

-In order to fatally overdose on caffeine you would have to drink about 40 cups of coffee. Your body would physically reject this much fluid, but this amount of caffeine injected intravenously would certainly do the job.
