The legal drinking age in Jamaica is 18. The majority of the information on the internet indicates that Jamaica is a place where IDs are not normally checked. However, if you’re not 18, then you shouldn’t be drinking alcoholic beverages to begin with. There is a reason why there is an age limit for drinking, or they wouldn’t have one. I, honestly would not want to take any chances of being in a foreign place, and attempt to do something that is illegal. Then again, I wouldn’t take the chance of doing anything illegal in a non-foreign place.
