I have these troublesome ideas it seems; imagining using hemp instead of petroleum. Next I'll want a 3D printed hemp machine gun, for all kinds of trouble!

yup..you potheads are just asking for trouble..that's why I don't take you serious.
as long as we're imagining...imagine a 3D printer that draws it's feedstock from polluted water. Lotsa chemicals floating around in there..that's why it's called polluted.
(hint: they're doing it in the lab as we speak...it's possible. All else is engineering and economics)

haha that's wise, to not take me seriously.

no personal offense...but I worked with some potheads back in the day.
I don't EVER want to do that again.
Unreliable doesn't BEGIN to describe them...and DANGEROUS as hell.

Don't worry, you won't have to work with such people; us dangerous unreliable potheads don't work anyway. You're safe!

yup I are.
I'm retired.
