*high five!*
There are SO many people out there who think pot is okay, there is nothing wrong with it, it was the cotton industry who sought to make it illegal, it helps with my back problems, blah blah blah.
As I think you are already aware of what I was exposed to (although I've never touched it myself), I can't stand the stuff. It is a trigger for me, and I've seen what it can do. It's not just just the drug and it's effects, but the people/children who have to be exposed to situations because of it.
It's good that YOU know it's not okay for you, despite what others might say about it not being a bad thing.
