Nicotine is a chemical found in tobacco products like cigarettes and vaping devices. When you smoke or vape, nicotine goes into your lungs and then quickly into your bloodstream. From there, it reaches your brain in about ten seconds.

Once nicotine is in your brain, it releases chemicals that make you feel happy and relaxed. But this feeling doesn’t last long, and soon, you may want more. That’s how nicotine addiction can start.


Cocaine is a potent stimulant that comes from the coca plant. People use it by snorting it, smoking it, or injecting it into their veins. It reaches the brain quickly, creating a sudden and intense feeling of happiness and energy.

However, these intense feelings only last a short time. This short duration often leads people to use cocaine again and again, leading to addiction.


Heroin is an illegal drug made from morphine, a natural substance taken from the seed pod of various opium poppy plants. When used, it enters the brain rapidly and binds to opioid receptors on cells. These receptors are located in many areas, especially ones involved in feelings of pain and pleasure and in controlling heart rate, sleeping, and breathing.

The rush from heroin use can lead to severe dependence and addiction. The need for more of the drug to achieve the same high can also put users at a high risk of overdose. Many individuals undergoing addiction recovery stages find that overcoming substance dependence involves a multifaceted approach, including counseling, support groups, and medication-assisted treatment.


Methamphetamine, often referred to as meth, is a powerful, highly addictive stimulant that impacts the central nervous system. It comes in several forms, including a white, odorless, bitter-tasting crystalline powder that dissolves easily in water or alcohol. Consumption creates a false sense of happiness and well-being-a rush of confidence, hyperactiveness, and energy.

The physical effects of meth can last 6 to 8 hours, after which it can lead to a severe “crash” or physical and mental breakdown. Prolonged meth use can lead to extreme weight loss, severe dental problems, and skin sores caused by scratching.


Alcohol, found in beverages like beer, wine, and spirits, is a legal substance that alters mood and behavior. It is rapidly absorbed from the stomach and small intestine into the bloodstream and affects the central nervous system.

High levels of alcohol consumption can lead to an array of health problems, from liver disease to various types of cancer. However, the most immediate risk of alcohol is its potential for addiction.
