An estimated 21 million people in the United States suffer from at least one addiction. That figure doesn’t take into account the friends, partners, and family members who fall victim to this disease that ravages the life of their loved one. There is an old-fashioned view that addiction and drug use is a sign of a lack of morality or weak character. This stereotype couldn’t be any further from the truth. Doctors almost unanimously agree that substance abuse disorders are diagnosable medical conditions.

In our experience, one of the most important aspects of treatment is helping clients to understand exactly what drug addiction is and how it works. The support and guidance of doctors and mental health professionals who can help you understand your condition is imperative. When you’re able to recognize the signs in yourself and acknowledge that you need addiction treatment, you’re ready to begin the healing process.

Are All Drug Users Addicts?

Not everyone who uses drugs is addicted to them, but the best method to avoid developing the condition is stopping before it gets to that stage. While there are risk factors that put some people at an increased likelihood of becoming addicted, it can happen to anyone. For many first time users, what starts off as occasional harmless fun becomes increasingly frequent until they find themselves embroiled in addiction.

High tolerance and sensation-seeking are two key genetic risk factors for addiction. These traits, along with smoking, drinking or drug use during your teenage years put you at the highest risk of developing a substance use disorder. Not all drug users are addicts, but the potential is there in everyone. In some cases, a traumatic life event can topple you over the edge. In other cases, repeat exposure alone is enough.

What Are the Most Addictive Drugs?

It’s not easy to quantify how addictive a substance is because each affects individuals in unique ways. Scientifically, some drugs have a higher risk of causing harm due to the effects they have on the body and mind.

Opiates and opioid painkillers such as heroin, fentanyl, oxycodone, hydrocodone, and morphine mimic naturally occurring chemicals in the brain called endorphins. The pleasure derived from this, along with how quickly your body adapts and becomes physically dependent, makes these the substances with the highest risk potential.

Benzodiazepines are widely prescribed painkillers and highly addictive. The fact that they’re not seen as hard drugs puts them in a particularly dangerous category. They also mimic naturally occurring chemicals in the brain called GABA. GABA affects the central nervous system, causing relaxation and sleep. Physical dependence is a likely consequence of long-term use of these drugs, which include diazepam (Valium) and alprazolam (Xanax).

From Enjoyment to Craving: The Science of Drug Addiction

No one who uses drugs wants to become addicted or believes it’s going to happen to them. A weakness with the way the human brain works is that it doesn’t differentiate between different types of pleasure. When you receive praise, get sexual gratification or enjoy food, a neurotransmitter called dopamine is released. Our brains are hardwired to respond to the release of dopamine by reminding us to repeat the experience that caused pleasure.

Over time, using drugs as a shortcut to pleasure results in a lack of naturally occurring dopamine as the brain gets used to the substance causing an influx. It takes more and more of the drug to achieve the same effect, which is known as tolerance. In some cases, the body adapts to the presence of the drugs to the point that being without the substance causes withdrawal symptoms.
