Was just curious if marijuana or hemp I suppose is an annual or a perennial. I have always heard it's an annual, however you also hear the reason we have so many wild hemp plants in the midwest is because they grew it during world war 2. If it were an annual when they stopped planting wouldn't all the plants have died off?

Annual
But it's literally a weed and weeds are pretty good about self-sowing. Plants got along just fine without humans for quite some time.
Hemp produces a wonderfully long and strong fiber, making it useful for a number of applications. Woven into cloth, it feels much like linen.

it is an annual.
like most annuals it produces millions of seeds per plant. a few of the seeds manage to sprout and mature every year.
if the US would recover form the cerebral-rectal-insertion problem, we would see hemp as a crop again.
every pound of fiber is a poubnd of oil that does not need to be used.
hempseed oil is an excellent feedstock for biodiesel, and has the highest yield per acre of annual crops (palm oil yield is higher.) With a good breeding program, oil yields for hemp can be improved even further.
Unfortunately this is unlikely to happen, pot prohibition will continue, and americas will have to stick to crystal meth.

Sorry guys. She's a perennial. For real.
Lives for years. Just don't kill her. Protect her.
