Not always smart to be dabbing mystery powders into your mouth, hence the dude who mentioned bromo's. But, if you do get that far, and it numbs you, safe to assume it's coke, or at least weakened coked so then by that standard, sell it to someone you know.. cheap.. even though it's kinda fucked with coke to be selling to the bloodline and friends... but hey you apparently need the money lol.
sucks for you foafoafoaf in SE ohio can pick up a g of good cut for 20-30 bucks if he felt so inclined but i know of the troubles cincy is having right now plus there have been some big busts in that area lately
I don't think the dabbing is gonna be a reliable enough guide. The key point is, only the area dabbed should go numb, otherwise it may be cut with novacaine, a common and more powerful local anaesthetic. However a tiny dab is still not gonna numb that far anyway; this advice tends to apply so you can differentiate between snorting a line and the back of your throat going numb as well as yours gums, and from snorting a line and your whole face and teeth going numb (which either means its BANGING BANGING BANGING coke or its cut to shit with novacaine). Problem is once you've got that far, you know how good it is anyway! I'd get a mate who does it to snort a line, if it's decent enough, he may prob just buy it then and there anyway. You're gonna need to way it though. But I would make sure it's coke first - that's a drug people particularly don't like to get screwed around with. It has a distinctive odour if its decent, but it can't really be described. Again, finding someone who knows their sniff could just take a whiff and let you know whatsagwanin.
Personally I think snorting unknown and unverified substances is a bad call. Kid may snort a fat line of 2ce. Hell even a skinny line of 2ce or a bump would not be a fun surprise if you're not expecting it.
Around me coke makes a killing because there is allot of ignorance as to size and quality. its not crazy to see walked on $20 bags that scale to 0.20g and $50s that scale to 0.40-0.50g but its called and accepted as 1.00g, its more or less ridiculous and kinda hard to believe considering my proximity to a large population but thats street lvl i guess...dnt sell drugs n dnt trust coke dealers but if you do either buy a 0.00g scale
^ and make sure it has a dry weight function on it cause i know a couple guys that like to get over on people using the dry weight instead of true weight, if your weighing out just a gram or half or even a teener the dry weight will show up a couple points less then the true weight
