I'll admit that I'm not as "plugged in" to what pop culture is pushing these days, so can't speak to that, but my own experience with cannabis puts it in a different light for me (which, given your experience, I bet you're not that eager to hear, but maybe others might be).
For me, cannabis fits between opioids and over the counter pain killers - neither of which I can take for pain that I get from nerve damage from a pretty severe injury from a few years ago. Cannabis is very effective at taking the edge off that pain so I can sleep. It doesn't make it go away, it just makes it less intense. Cannabis is by no means benign - anything that can do what it does to my pain isn't "safe". I treat it with the same respect and responsibility I would with other medications. It's not perfect, and has its own risks, but in my case, it's beneficial.
Again, I really am sorry for you. Not so much because you can't enjoy cannabis, but because of what you have to deal with now.
