Amount: • Alcohol generally moves into the bloodstream faster in females than in males. Food: Rate of Intake: • A smaller person feels the effects of the same amount of alcohol faster than a larger person does. Gender: • • As the amount of alcohol consumed increases, the level of alcohol in the bloodstream rises. Medicine: • Alcohol can interfere with the effects of medicines, and medicines can heighten the effects of alcohol.

ALCOHOL AND DRUG INTERACTIONS • • Alcohol can change the effect of medicines – these interactions can lead to illness or death. Medicines that may cause reactions have warning labels that advise people not to use alcohol. • Note these typical alcohol-drug reactions: • The body may absorb the drug or alcohol more slowly, increasing the length of time that alcohol or drug is in the body. • Alcohol use can decrease the effectiveness of some medicines, and increase the effectiveness of others. • Enzymes in the body can change some medications into chemicals that can damage the liver or other organs.

So even if someone is unconscious, their blood alcohol level will still rise. This increases the risk of alcohol poisoning. • Symptoms of alcohol poisoning: • • Mental confusion and stupor • • Irregular heartbeat Coma and inability to be roused Vomiting and seizures Slow respirations (10 seconds between breaths OR fewer than 8 breaths per minute) Hypothermia or low body temperature
