If a young person drinks 3-4 times per month, this is harmful use and very serious.

National Health Service, Alcohol Misuse
up to 112 g/week up to 112 g/week 8 This applies to adults who drink regularly or frequently i.e. most weeks. The Chief Medical Officers’ guideline for both men and women is that: 
• To keep health risks from alcohol to a low level it is safest not to drink more than 14 units a week on a regular basis. 
• If you regularly drink as much as 14 units per week, it is best to spread your drinking evenly over 3 or more days. If you have one or two heavy drinking episodes a week, you increase your risks of death from long term illness and from accidents and injuries. 
• The risk of developing a range of health problems (including cancers of the mouth, throat and breast) increases the more you drink on a regular basis. 
• If you wish to cut down the amount you drink, a good way to help achieve this is to have several drink-free days each week. 
This applies to drinking on any single occasion (not regular drinking, which is covered by the
weekly guideline). The Chief Medical Officers’ advice for men and women who wish to keep their short term health risks from single occasion drinking episodes to a low level is to reduce
them by: limiting the total amount of alcohol you drink on any single occasion, drinking more slowly, drinking with food, and alternating with water, and planning ahead to avoid problems e.g. by making sure you can get home safely or that you have people you trust with you. 
The sorts of things that are more likely to happen if you do not understand and judge correctly the risks of drinking too much on a single occasion can include: accidents resulting in injury, causing death in some cases, misjudging risky situations, and losing self-control (e.g. engaging in unprotected sex). The risks of injury to a person who has been drinking recently have been found to rise between two and five times when 5-7 units (40-56 g) are drunk in a 3-6 hour period. 
Some groups of people are more likely to be affected by alcohol and should be more careful of their level of drinking on any one occasion for example those at risk of falls, those on medication that may interact with alcohol or where it may exacerbate pre-existing physical and mental health problems.
If you are a regular weekly drinker and you wish to keep both your short- and longterm health risks from drinking low, this single episode drinking advice is also relevant for you.

14 To help Americans move toward a healthy dietary pattern and minimize risks associated with drinking, adults of legal drinking age can choose not to drink or to drink in moderation by limiting intakes to 2 drinks or less in a day for men and 1 drink or less in a day for women, on days when alcohol is consumed. This is not intended as an average over several days, but rather the amount consumed on any single day. Binge drinking, defined as 5 or more drinks for the typical adult male or 4 or more drinks for the typical adult female in about 2 hours, should be avoided.
The Dietary Guidelines does not recommend that individuals who do not drink alcohol start drinking for any reason. There are also some people who should not drink at all, such as if they are pregnant or might be pregnant; under the legal age for drinking; if they have certain medical conditions or are taking certain medications that can interact with alcohol; and if they are recovering from an alcohol use disorder or if they are unable to control the amount they drink. If adults age 21 years and older choose to drink alcoholic beverages, drinking less is better for health than drinking more.

These guidelines are specifically for low risk of developing alcohol use disorders. 
If you have a health problem or take certain medications, you may need to drink less or not at all.

Drinking is never completely safe, but if you decide to do it, try to reduce risks as much as possible. To do so you can calculate your units and keep in mind the limits. 
Do not exceed these limits. If you are accustomed to drinking, avoid alcohol for at least two days each week.
