Those who drink in Saudi Arabia will usually be consuming something of unknown strength. Most alcoholic drinks come from the homes of amateur brewers. This makes it impossible for people to safely judge the amount they are drinking. The most popular spirit in Saudi is siddiqi – it is often shortened to sid. This varies in strength but is a lot stronger than standard spirits available in the west. Sid can be as strong as 90% percent alcohol, and it often also contains impurities. Alcohol poisoning is common when people are drinking such strong concoctions.
