Drug A - Z
Alcohol (ethanol or ethyl alcohol) is the ingredient found in beer, wine and spirits which causes drunkenness. Alcohol is formed when yeast ferments (breaks down without oxygen) the carbohydrates or sugars in different food e.g. wine is made from the sugar in grapes, beer from the sugar in malted barley (a type of grain), cider from the sugar in apples, vodka from the sugar in potatoes, beets or other plants.
Ethanol dissolves easily in water, so it can be rapidly absorbed throughout the body in the blood. Alcohol passes through the placenta to the unborn child and is also present in breast milk when a mother drinks.
Alcohol is the most widely used social drug in New Zealand. Alcohol is classed as a depressant. However, at low doses it acts as a mild stimulant. As concentrations in the bloodstream increase, stimulation gives way to sedation, stupor, coma and finally death.
The amount of alcohol consumed when drinking depends on how much alcohol is in s a particular type of drink and how many drinks you consume. The standard drinks measure is a simple way for you to work out how much alcohol you are drinking. It measures the amount of pure alcohol in a drink. One standard drink equals 10 grams of pure alcohol.
Initially when you drink alcohol, you experience a feeling of pleasure and relaxation. The more you drink, the higher your blood alcohol level becomes, and your body’s reactions begin to slow down. You may experience slurred speech, inability to walk straight, and impaired judgement and co-ordination.
Alcohol can be dangerous in smaller amounts if it is used in combination with other drugs
There are recommended guidelines for low risk drinking. The more you drink over the recommended amount the more at risk you are. Some of the short-term effects on your health may include:
•mood and personality changes
•missing work due to hangovers, headaches
•high blood pressure
Other, long-term effects may include;
•major damage to the brain, the central nervous system, digestive system, heart and liver
•increased risk of some forms of cancer
•prone to depression

Hurting others or being hurt your self
Binge drinking can lead people to be more likely to hurt others round them or to do things they wouldn’t if they were not intoxicated. Examples include:
- Domestic violence and abuse
- Other criminal offending
- Relationship problems
- Regretted sexual encounters and unsafe sex.
An intoxicated person is also more vulnerable to becoming a victim of violence. It is much harder to keep yourself safe.
Psychological dependence occurs when using a drug becomes more important than other activities in a person’s life. Physical dependence upon a drug occurs when a person’s body is used to functioning with the drug present in the system. Alcohol dependence affects physical and mental health, and causes problems with family, friends, and work. It is characterized by a mental and/or physical need to consume alcohol in order to prevent the pains of withdrawal. Withdrawal symptoms occur when a person dependent on a drug stops using it or significantly cuts down the amount they are using. people who have been drinking for a long period of time, or drinking frequently, or drink heavily when they do drink, will experience some form of withdrawal symptoms if they stop drinking suddenly.
If you are concerned that you or someone you care about may be dependent on alcohol call the Alcohol Drug Helpline for confidential professional help.
Impact on the unborn child or breast feeding baby
Alcohol has the potential to cause harm to the unborn child and also harm to the baby whilst breastfeeding. Due to this, it is recommended to not use any level of alcohol during pregnancy and whilst breastfeeding.
Drinking significantly more than the body can metabolize and eliminate often results in alcohol poisoning, which in some instances is fatal. Binge drinking (consuming more than the recommended guidelines at one sitting) can also lead to alcohol poisoning. Nausea and vomiting are two of the first alcohol poisoning symptoms a person with an alcohol overdose will experience. If someone you know is unconscious due to drinking put them in the recovery position and call an ambulance.
It is illegal to drive a motor vehicle with a blood alcohol level over the legal limit. Current legal limits are:

The Health Promotion Agency has designed alcohol drinking advice to help you make an informed choice and help keep your risk of alcohol-related accidents, injuries, diseases and death low.
Low- risk is not, however, no-risk. Even when drinking within the low-risk limits, a range of factors can affect your level of risk including the rate of drinking, your body type or genetic makeup, your gender, existing health problems, and if you are young or an older person.
Reduce your long-term health risks by drinking no more than:
- two standard drinks a day for women and no more than 10 standard drinks a week
- three standard drinks a day for men and no more than 15 standard drinks a week
AND at least two alcohol-free days every week.
Reduce your risk of injury on a single occasion of drinking by drinking no more than:
- four standard drinks for women on any single occasion
- five standard drinks for men on any single occasion
