coppin in newark can be extremely risky and even dangerous, or if you know what youre doing it doesn't have to be all that bad. if you just go there with no connect or phone numbers, looking to buy off the street, then you are taking a big risk. cops know that tons of people come in from the suburbs every day to buy dope. youll be stopping your car, talking to random people and looking around like a lost dog, all dead giveaways.
but with that said, if you have a good idea of what youre doing, or have someone (not here) help you out, give you pointers, and some directions, you might be okay. if you know the good spots and have any experience buying in an open air market, those are big plusses. but i doubt in your situation thats likely, so id have to say for you itd probably be very risky. you wont feel safe at all and you could easily get pulled over. you could probably get number though and figure out a decent spot to meet, but that will take a some time. and yes, the dope is ridiculously good, but still, you likely wont find the fire your first time around.
you should really think about it now before you just get sick and decide against your better judgement to go just because you have no other options. your best option may very well be to play it safe and try to find elsewhere, until you get a better understanding of the game in newark.
hope i helped you out a bit
