Drug use can have many different effects depending on the specific drug or drugs used, how they are taken, how much is taken, the person’s health, and other factors. Short-term effects can range from changes in appetite, heart rate, or overdose. But it can also have long-term effects such as heart and lung disease, memory problems, mental disorders, and even cancer.
