My dealers get it straight from growers in Chicago all the time.
Grower>Dealer>Me
Oh, and I smoke in my house as well. It's extremely easy, especially at night (obviously). I toke in the basement, and my parents are 2 stories above me in their rooms, so it's all good.
Also, eye drops are a must
Oh and like Yuki said, I made a lot of new friends too. This one night, my friend and I brought our bong and weed to another friend's backyard. I met 6 new people there, and my current dealer there as well. Now because of that, we noticed each other in our study halls and what not haha
