Not all people who abuse the same drug suffer in the same ways. Your body and your brain chemistry are different from the next person’s. Frequency, longevity, and amount of consumption also depend on the person. One thing is true for everyone, however: Substance abuse is dangerous.

Substance abuse can lead to addiction and physical dependence.
The word “addiction” is often coupled with the word “dependence.” Addiction describes the emotional and social factors that compel a person to abuse a drug. Dependence captures the physiological effects of long-term drug usage, such as withdrawal. A person’s addiction may cause them to spend their savings to buy drugs, for example. A person’s physical dependence on a drug may cause them to shake or tremble until they take another hit. Addiction and physical dependence on a substance can be life-threatening. If the abused substance doesn’t kill you, it will degrade your health and your mental well-being until you seek treatment.
Substance abuse affects everyone around the person who uses.
If someone abuses alcohol or another drug, their roommates, hallmates, classmates, professors, friends, and family will all be affected. They care and want their loved one to be safe and healthy.
- If you are addicted to or dependent on a drug or alcohol: Consider seeking help for your specific situation. Alcohol abuse and alcoholism are treated differently than other substance abuse. Similarly, nicotine can create serious addictions and dependencies, but you can treat them.
- If you know someone who might be abusing a drug or alcohol: Learn about their addiction. There are hundreds of substances out there, and abuse of one of them does not necessarily look like abuse of another. Alcohol abuse, nicotine dependence, and abuse of other substances all present their own hurdles. Understand your loved one’s struggle so that you can help them toward recovery, and don’t forget to take care of yourself too.
Substances behave differently, and so do human bodies.
