i smoke carts literally all day everyday (i buy bulk disty and fill myself) and aside from psychological addiction theres no actual physical harm. marijuana is effectively harmless especially if used as you describe. feel free to read soem studies but marijuana has at worst caused respiratory issues at doses like 100000mg that lasted a few hours then theyre fine with no damage.
decade long daily users stop for a month and lung health stays/goes back to baseline.
dont let the propaganda scare you but also dont let your impulses control you theres good and bad parts to everything you have to figure it out tho.
before anyone says dont smoke everyday its bad. i know more about my body than you people ever will. and i know its bad but im not in a good place. judge my circumstance not my actions im working on it.
