Its also a really funny idea.
I get it you think to be a weed dealer you need to be some kind of hardened criminal who commits all sorts of various crimes or whatever, but im here to break it to you that the hollywood criminal drug dealers youre imagining dont really exist. Many people do all sorts of illegal things because we live in a country with many overly restrictive and draconian laws. Very few of those people are the dangerous criminals you are imagining. Most of them are regular people who dont have the religious reverence for arbitrary laws that some other memebers of our society have.
Pretty much every grow bust they find guns, etc. Even in countries where it should be almost impossible to get those guns.
This was decades ago so I suppose its possible that in the intervening time everyone involved in the weed trade has reverted to the violent Hollywood drug dealers of yore, though I find that unlikely.
There really is this perception among more sheltered circles that if you break some given law you must be some kind of stoic gangster type. Its really not true.
Maybe in the 70s when weed came in bricks shipped in by the cartel. During that time the people moving pounds were probably actually dangerous people. During my time as a delinquent though, weed was grown in the mountains by families who were more likely to be caught donating to the local homeless shelter/passing out food and blankets to the homeless than they were "using violence on people on the street"
I promise you, you dont need to live in fear of weed dealers. They are really not that dangerous.
You must not have met many weed dealers before have you? Specifically the examples where a "drug dealer" would be violent are so divorced from my own lived experience that it really makes me wonder if this is how some of society really thinks weed dealers act like.
