Quality bud is not hard to find, you may not have the selection that you could get in colorado or washington but good hook ups usually have 2 or 3 medical strains to choose from.
Dabs are common in Roskie, I don't know about in other dorms, but good oil is usually brought in from elsewhere so it can occasionally be hard to find. Lots of people have rigs too if you don't.
Smoking in the dorms is honestly not an issue as long as you're not stupid about it. I'm blazing a bowl with my roommate as I write this. Towel door + fan at window + smoke buddy + spray+ keep it semi quite and you'll never get caught, anymore I just crack the window and turn on my fan.
