5 Naira is dead under Buhari?: Is it true that 5 Naira can no longer afford anything in Nigeria?

I'm asking because a blog visitor in Nigeria told me that he had 5 naira in his wallet and was moving around for a whole week looking for what to buy with it, but it couldn't afford anything and he later had to dispose off the money in the bin. He said even the cheapest sweets or biscuits in the market now goe for
10 naira and above. Since President Buhari resumed office.

Can 5 naira buy anything in your present location or state?
