Clouds do still remain on the Jamaican horizon, however. Perhaps the biggest concern for outside observers is the lack of a fully functioning anti-doping body on the island.
First mooted in 2005, the Jamaican Anti-Doping Commission (Jadco) remains an organisation with more good intentions than testing kits. Repeated promises have been made to fast-track the necessary legislation and funds through parliament but three years later all that is clear is the island's sprinters are faster than its lawmakers.
Neither the World Anti-Doping Agency (Wada) nor the Jamaican authorities have been able to confirm to BBC Sport that Jadco is actually operating yet. The situation is further muddied by Jamaica's decision to opt out of the Wada-approved Caribbean Regional Anti-Doping Organisation (Rado).
The only organisation currently undertaking widespread testing in Jamaica is the International Association of Athletics Federations (IAAF).
The Monaco-based governing body has raised its game in recent years, and now actively targets countries without adequate anti-doping regimes of their own (Jamaica is the IAAF's fifth most tested nation), but question marks remain over the effectiveness and transparency of its operations.

Dr Adrian Lorde, the head of the Caribbean Rado which Jamaica stayed out of, has voiced concerns about the amount of testing done on the island.
When asked by BBC Sport if Jamaica was testing enough, he replied: "I don't get that impression. I would like to think they do that testing there but I really don't know.
"I don't know what level of certification their doping control officers have. We really don't know what is going on in Jamaica.
Damn our fucking borders, damn them all to hell
