More deaths, illnesses and disabilities stem from substance abuse than from any other preventable health condition. Today, one in four deaths is attributable to illicit drug use. People who live with substance dependence have a higher risk of all bad outcomes including unintentional injuries, accidents, risk of domestic violence, medical problems, and death.
Health Problems
The impact of drug abuse and dependence can be far-reaching, affecting almost every organ in the human body. Drug use can:
Weaken the immune system, increasing susceptibility to infections.
Cause cardiovascular conditions ranging from abnormal heart rate to heart attacks. Injected drugs can also lead to collapsed veins and infections of the blood vessels and heart valves.
Cause nausea, vomiting and abdominal pain.
Cause the liver to have to work harder, possibly causing significant damage or liver failure.
Cause seizures, stroke and widespread brain damage that can impact all aspects of daily life by causing problems with memory, attention and decision-making, including sustained mental confusion and permanent brain damage.
Produce global body changes such as breast development in men, dramatic fluctuations in appetite and increases in body temperature, which may impact a variety of health conditions.
