The problems you may develop if you continue using alcohol or other drugs depend on many different factors, including: the drug(s) being used, how you use the drug, how often you use, and your weight, age and general health.
Short-term problems can include a greater risk of injury while affected by drugs, social consequences of poor behaviour resulting from your drug use, taking too much of a particular drug (overdose) which can be fatal, and problems caused by stopping drug use all of a sudden, i.e. experiencing symptoms of withdrawal.
Long-term problems related to drug and alcohol use can include serious and debilitating physical issues (including irreversible organ damage), mental health issues, and difficulties with employment, education and relationships. Some people also face legal problems as a result of their drug or alcohol use.
