Strange post, everyone knows if you walk around Nana after, say 2am, you will see dozens and dozens of African dudes all wanting to sell you cocaine with prices set at 3000, 5000, and 7000. I have lost count of the amount of times I have been approached by them. The quickest way to get rid of them is to ask them what the purity level of what they are selling is, because they can't answer, they simply don't know. And with 4 decades of buying that <deleted> behind me, that is a question you really have to know the answer to before buying it. Most likely what they are selling is so heavily cut, it's rubbish, and you won't get much out of it. We had the same problem with south africans about 10 years ago, and the stuff they sold was not worth touching, and they were being helped by the police.
