Cocaine and heart-attacks

[rbenuck4]

Cocaine works very differently than caffeine. Cocaine basically affects the reuptake of norepinephrine (which directly increases your heart rate). So in other words, the Norepinephrine stays in your system for longer and thus works overtime.

Caffeine on the other hand, is a stimulant (and a minor one at that). It acts primarily by blocking adenosine receptors (adenosine is responsible for , bradycaardia, hypotension, hypothermia, and attenuation fo the responses of the heart, etc... Caffeine has other affects as well, but this is the main one physiologically.

Anyway, long story short, cocaine is MUCH worse for you than a huge load of caffeine.
