but i don't know how long hemp has been cultivated.

Prolly just as long as we've had high priests and priestesses.


yeah, but...

the variety of hemp that is good for fiber is the tall stalky weed.. (it grows 8 to 10 feet high!) and the short, bushy, early flowering type is better for, well "medicinal" purposes. hemp fiber plants do well in more northern climates. (its a big fiber crop in canada!) medicinal plants like more sun and milder weather, (the tropics).

no doubt there is over lap in where they can grow.. and perhaps the plants were less distinctive in times past, but fiber hemp is really smokable. it has almost none of the 'active' ingredient associated with its cousin.
