You from the city? For 30 you should get a fat qtr. May be shakey/seedy or it may be some straight mids depends on the guy. Most street dealers got that shake bullshit. I get o's of good mids all day for a bill.
I can get this stuff called Machine Gun for 30 a quad. Way better than shwag. Hardly any seeds. I'd almost compare it to KB. Smells good, and gives a real nice high. I don't ever buy it though. I did back in HS when I was poor though.
Sorta im near Ann Arbor I only go into the city when I have to. My guy said he was gonna get some good purps soon guess ill just wait it out. Sucks being dry.
Weed is weed bro. If you want to toke, buy that quad. I'm sure you'll be getting better than shwag for 30, cause I can buy quads of shwag for 20. Even if it is shwag, it'll still get you high.
