I have found that I can get overwhelmed very easily and my heart will start pounding. At that point I'm set to go off on people to which I'll of course apologize after the fact. Sucks being like that. Cenex by phat panda is so dense with thc that i only need a micro toke and my heart rythms return to normal. I sold kilos in my day so it's not about getting high anymore. I just want to be nice to everyone and have a clear head while i'm at it. Like i said, changed my life.

Cannabis wasn't smoked until about 4500 years ago in China, and not until 3000 years ago in Egypt, by which point civilization had already been around for thousands of years.

Cannabis was used mainly for its fibres up until the modern era. The potency was not very high until selective breeding during the Arabic era.

In addition, there were MANY other more powerful drugs used much more extensively in the past, including opium that was in use around the Mediterranean by 8000 years ago, and psychedelic mushrooms by 38,000 years ago. Psychedelics are much more likely to have impacting human thinking,

All mammals get high from cannabis smoke.

This isnt news.

^ basically Cave men would put it in their fire's.

You just defeated your own argument.

Your point was "evolutionery theoy suggests the simple fact that our brains have canabanoid recepters and are so blatently wired for Cannabis and other drugs suggest humans have done drugs for tens of thousands of years."

If the ancestors of humans evolved the receptors as far back as 250 million years ago, then it only suggests that early mammals developed receptors. It doesn't at all suggest that humans smoked any cannabis in neolithic and paleolithic times.

We've all smoked weed before, it does not improve intelligence. It gives you the giggles, the munchies, and sometimes a twitch and tunnel vision.

The actual reason that people began building cities was because of the evolution of easy to harvest grain aqround 13-15,000 years ago. The reason behind the ease of harvest was because the bunches larger and looser against the plant, making them much easier for people to collect. Shortly after that type of grain appears, humans began harvesting it, making breads, and giving up the nomadic lifestyle to become farmers. The earliest records of this occurred in the region of Asia Minor and the Middle East, then spreading quickly to Egypt and Asia. This period was known as the Neolithic revolution.

Within these settlements, there was time to explore and expand knowledge, and soon metal working developed, and the mixing of tin and copper to create bronze brought on the iron age.

Later, searching for a more common metal, iron mining developed, and those regions entered the iron age. The development of iron tools gave rise to the classical age and the great and powerful Ancient Empires like the Athenian Empire, the Persian Empire, and the Roman Empire.

So while a plant DID in fact cause humans to become civilized, it was the evolution of THIS plant:

Not weed... WHEAT! :D

Although, wheat based food can solve one of your weed based cravings.
