You can bring drinking alcohol (ethanol) to Jamaica. The bottle image on page 1 shows 95% (or 190 proof). That's the max achievable by distillation and is what's commonly referred to as "alcohol" in your chemistry class. It's the only solvent that I would use for medicinal preparations. I've used overproof in the past.
When I lived in Corning NY, we used to make the short drive to PA to hit the State Store to buy pints of Pharmco Grain Alcohol @ 190 proof. Makes very sneaky Screwdrivers. When you hear 60Hz buzzing in your head, you've had too many! Not much of a hangover, except for the dehydration!
