How Different Drugs Affect the Body

Updated on August 8, 2022

When most people think of drug addiction, they often only think of illegal drugs like cocaine and heroin. However, there are many legal drugs that can be just as addictive and dangerous as their illegal counterparts, including prescription medication like painkillers and tranquillisers.

In this blog post, we’re going to take a look at how different drugs affect the body, both legal and illegal. If you think you may have a problem with addiction, you can always seek professional drug help in Perth.


Starting with alcohol, it’s no secret that this is a substance that can have serious consequences on your health if abused. Alcohol addiction can lead to liver damage, heart disease, cancer, and a whole host of other problems. It can also cause accidents and injuries due to its effects on the brain, which include impaired judgement, slowed reaction times, and slurred speech.


Marijuana is another drug that is often thought of as being harmless, but it too can have harmful effects on your health. Smoking marijuana can lead to lung damage, as well as problems with memory, learning, and mental health. The active ingredient in marijuana, THC, can also increase your heart rate and blood pressure, which can be dangerous for those with heart conditions.


Cocaine is a highly addictive illegal drug that can have devastating effects on your health. The short-term effects of cocaine use include increased heart rate and blood pressure, as well as anxiety and paranoia. Long-term effects of cocaine use can include heart disease, stroke, and seizure.


Heroin is another illegal drug that is highly addictive and dangerous. Short-term effects of heroin use include slowed breathing, drowsiness, and confusion while long-term effects of heroin use can include liver and kidney disease, as well as collapsed veins.

Prescription medication

Prescription medication like painkillers and tranquillisers can also be addictive and dangerous. These drugs can cause drowsiness, slowed breathing, and impair judgement. They can also lead to accidental overdose, especially when taken in combination with other drugs or alcohol.

Seek help if needed
