Personal ethics.
Being outlawed might be the reason for the criminal activity but the narcissism of the end user is what drives demand.
After all when you face God and he shows you the victims of your use then what is your response? “Not my fault?”
If you knew that someone got shot for every jar of peanut butter you ate, are you still going to be eating peanut butter?
So what if someone lives on a farm and grows their own? I don’t see a lot of victims there.
A lot of bad things happen up stream in the supply chain of things we use every day. Whether it’s miners getting black lung to supply us with coal or steal workers losing body parts to the mill or fishing boats sinking or drug cartels having their little wars.
If God is going to hold all of the upstream “victims” of our various usages against us I don’t think any of us are making it to heaven.
