Oxygen and water are both poisonous, but so is everything in high quantities; however, alcohol is not straight poison for your body.
Did you know there is no difference in effect on the liver between alcohol and acetaminophen?
Also, nicotine is used as a pesticide, but many people still use it anyway, while it only takes 60mg (give or take depending on the person) to OD.
There are many things that truly are poisonous to us, but we still use them in every day life anyway.

I do not see why it is tragic that it is legal. In small doses, alcohol is fine for you, even has quite a few healthy effects on the body (if you want to believe the science behind it), but, in large doses, that is when things take a turn for the worse, just like everything else in the world. Too much of anything is going to be bad for you. It is when people do dumb **** while under the influence that tends to make the drug look bad, not the person.

I do not remember where I was going with this.
