Can weedheads live a productive life?

...in their view, sure.

Yes if they sell weed

I only smoke when Its time to wind down ..I can’t smoke in the mornings because it makes me lazy and forgetful as shit lol

Some can ... depends on what you call "productive"

I think so. If you have the determination, weed doesn’t make you tired right away, my dads been smoking strong his whole life, and I did everyday for a while. Held a job, went to college, why couldn’t one?

No
