Well the Bible does say obey the laws of the land so it would be wrong in some sense but I dont think you'd be held accountable because the law is bullshit (even though its still wrong to disobey it lol). But as for selling it to people, no. marijuana is not harmful. Now if you were selling meth or angel dust you might as well be the grim reaper and you would be held accountable. It's almost like assistant suicide even though the people choose to buy it your still the supplier which means if you never sold it they couldnt get it (atleast not from you).

But my family is Christian so this is why I know what the Bible says but I am not a Christian, I'm an Atheist. I think religions are just ridiculous. Humans claimed to have supernatural powers? Healing the blind, curing the deaf? Bringing back a dead man once his organs has already stopped?? Turning water to wine? Walking on water? I think not.
