Can you spend us dollars in cuba?

As of my knowledge cutoff in September 2021, it was not possible to spend US dollars in Cuba. The US dollar was, and still is, not a legal tender in Cuba. Instead, the official currency of Cuba is the Cuban peso (CUP) and the convertible peso (CUC), which is pegged to the US dollar. Visitors to Cuba were required to exchange their foreign currency for either CUC or CUP upon arrival in the country.

However, please note that this information may be outdated as US-Cuba relations are subject to change. For the most up-to-date and accurate information, I recommend consulting a reliable and current source on Cuban currency regulations and policies.
