Have you considered trying to grow your own? It only takes 3-4 plants in a closet to make enough for a couple people, you can control what they're treated with, and it's market proof. And generally per weight it's cheaper than buying at a dispensary...
I’ve never gotten further than attempting to germinate the random seed I’ve found. I believe growing yourself is still technically illegal in NJ oddly enough, although I’m not overly concerned with that part. Definitely something to consider.
