I did edit the above post but in the end I was too late.
Basically maybe in Jamaica, and Jamaica alone, there is no punishment for cannabis,
I did however give a perfect example of legal action happening inside of the carribean with the seizure of a yacht on the cayman islands, which are based inside of the carribean.
I was merely giving an image of the carribean as a whole, that it is illegal even there, and it is punished, even if it is a rare occurance.
