I suspect that our definition of top grade and mid grade is different also. What you consider top shelf in Colorado might go in Ohio as good mids.

There is for sure more BAD weed in Colorado than Ohio.

So I guess you are lucky that you have a good network to buy from. I got tired of buying weed a long time ago so I learned how to grow.

What are you studying in school? I have an advanced business degree, I went 4 years without smoking weed when I was in school.
