As has been said several times, it is illegal, however enforcement is at the whim of the Police. I've seen Police walk by and either not care or not notice, on the other had, I have seen tourist arrested for smoking. Discretion is the operative word.

However, if you are busted, the good news is that the Negril Jail has a 24/7 bar on the property. Cash only, no credit!! They have a generator so they always have very cold beer, even when the current is out!

Enjoy,
