Drinking rubbing alcohol is extremely dangerous and can lead to severe health problems, including death. Rubbing alcohol is usually isopropyl alcohol, which is poisonous and can cause terrible gastric disturbances if ingested. Isopropyl alcohol is only slightly more toxic than ethanol, which is the type of alcohol found in drinks, but it is still very dangerous to consume. Drinking rubbing alcohol can cause acetone to build up in the body, which can lead to headaches, dizziness, vomiting, and even coma if taken in large enough quantities. It is important to note that rubbing alcohol is not the same as drinking alcohol, and they have different effects on the body. Therefore, it is never safe to drink rubbing alcohol, even if it is diluted with water or other liquids. If someone drinks rubbing alcohol, the best thing to do is to get them to the hospital immediately.
