Tourism in Ocho Rios, as with the other Jamaican town's is relatively safe, with violent crime being low and the main safety concern being the availability of drugs. Marijuana and hash are prevalent all around Ocho Rios and it is highly likely that travelers who might even remotely appear like people who might be interested in purchasing such drugs may be approached for sales.  While the drugs themselves are generally safe (not tampered with), it should be noted that both possession and use of drugs is illegal in Jamaica and you could be facing jail time if you are caught with drugs in Ocho Rios. 

Other than drugs, crime is relatively low in Ocho Rios.  It is virtually unheard of for tourists to be bothered by any sort of violent crime.  That violent crime which occasionally does occur in Jamaica is usually in the ghetto areas of the island and not in the tourist areas so Ocho Rios travelers are safe.  Pick pocketing and purse snatching do occasionally occur and normal foreign travel precautions should be taken in regards to these situations.  One action practiced while in South America was to keep wallets in front pocket, do the same in Jamaica.

In terms of health, there are no special precautions which need to be taken by travelers to Ocho Rios.  The water in Jamaica is safe to drink particularly in the resort areas as it is filtered and purified by modern methods.  Therefore, it is safe to drink straight from the tap, but if you do prefer to drink bottled water it is widely available. look/ask for brands like Catherine’s Peak, which is bottled in the Blue Mountains, Wata, Jamaica Blue Mountain and Mivida.

While in Jamaica use your common sense in regards to weather conditions and make note of the emergency services available in Ocho Rios in case an emergency should occur.
