What is Substance Use Disorder?

Substance use disorder (SUD) is a medical condition that involves the continued use of alcohol or drugs despite negative consequences. It is not a lack of willpower or a moral failing. Instead, it is a complex condition influenced by brain chemistry, genetics, environment, trauma, and mental health. People living with substance use disorder may find it difficult to control how much or how often they use a substance. 

Unfortunately, the substance can become central to a person’s daily life and affect their work, school, physical health, and relationships. Like other chronic health conditions, substance use disorder can range from mild to severe.

 Types of Substance Use Disorder

Substance use disorder can involve a wide range of substances. Each of these influences the brain and body in different ways. Some substances are legal or prescribed by medical professionals, while others are illicit or used primarily in social settings. Regardless of how a substance is obtained, repeated misuse can lead to dependence and, eventually, addiction. 

Alcohol

Alcohol use disorder involves the problematic use of alcoholic beverages, often progressing gradually over a period of time. Because alcohol is widely available and socially accepted, warning signs may be easy to miss until drinking begins to impact a person’s quality of life. 

Opioids

Opioid or opiates is a class of drugs that include both prescription pain medications and illicit substances. These drugs act on opioid receptors in the brain, reducing pain but also creating strong feelings of euphoria. Misuse carries a high risk of dependence, addiction, and overdose. Types of opioids include:

  • Heroin
  • Fentanyl
  • Oxycodone
  • Hydrocodone
  • Morphine
  • Codeine

Stimulants

Stimulants increase alertness, energy, and focus. While some stimulants are prescribed for medical conditions, misuse can place significant strain on the heart and nervous system and may lead to anxiety, paranoia, or crashes in mood and energy. Some examples of stimulants include:

  • Cocaine
  • Methamphetamine
  • Prescription stimulants such as Adderall or Ritalin

Benzodiazepines

Benzodiazepines are medications often prescribed for anxiety, panic disorders, or insomnia. However, dependence can form, especially when taken long-term or without proper medical oversight. Benzo withdrawal symptoms can be particularly intense. These medications include:

  • Xanax
  • Valium
  • Ativan
  • Klonopin

Prescription Drugs

Prescription drug addiction includes the misuse of medications that are intended to treat legitimate medical conditions. This may involve taking higher doses than prescribed, using medication without a prescription, or combining medications in unsafe ways.

Marijuana and Kratom

Marijuana and kratom are often perceived as low-risk or natural alternatives, but they can still lead to substance use disorder for some individuals. Regular or heavy use may affect motivation, memory, mood, and emotional regulation.

Party Drugs

Party drugs are commonly used in social or recreational environments, such as clubs, festivals, or parties. While some people view these substances as occasional or harmless, they can carry serious physical and psychological risks. This is especially true when they are mixed with other substances. The following are commonly used party drugs:

  • MDMA or ecstasy
  • LSD
  • Psilocybin mushrooms

How is Substance Use Disorder Treated?

Effective treatment for substance use disorder meets people where they are in recovery and adjusts as their needs change. Many drug and alcohol rehabs include a combination of medical care, therapy, and ongoing support. Common treatment programs for SUDs include: 

  • Detox: Detoxification is often the first step in treatment. During detox, the body clears the substance while medical professionals manage withdrawal symptoms. This process helps create a safer and more stable starting point for further treatment.
  • Residential Treatment: Residential or inpatient treatment provides a structured environment where individuals live on site while receiving comprehensive care. This level of support can be helpful for those with severe substance use disorder or those who need a break from daily triggers and stresses.
  • Partial Hospitalization Program (PHP): A partial hospitalization program (PHP) offers intensive treatment during the day while allowing individuals to return home or to supportive housing in the evenings. Sessions typically take place five days a week and last the majority of the day.
  • Intensive Outpatient Program (IOP): An IOP provides several hours of therapy each week while allowing participants to continue working or attending school. Participants commonly go to treatment three to five days, with evening programs sometimes available.
  • Outpatient Program (OP): Outpatient treatment involves regular therapy sessions with more flexibility. It allows individuals to assimilate back into daily life while still receiving the support they need. 
  • Aftercare: Aftercare focuses on maintaining recovery after formal treatment ends. This may include continued therapy, peer support groups, sober living, and alumni opportunities.

Therapies for Substance Use Disorder

When healing from substance misuse, individuals typically participate in a combination of evidence-based interventions and holistic healing strategies. These different approaches address emotional health, behavioral patterns, and trauma, helping people build a strong foundation for long-term recovery.

  • Trauma Therapy: Trauma therapy helps individuals process past experiences that may have contributed to substance use in a safe and secure setting.
  • Holistic Therapy: These strategies focus on healing a person as a whole and may include mindfulness practices, yoga, meditation, and nutritional guidance.
  • Family Therapy: Addiction affects the whole family. Family therapy works to improve communication, address unhealthy dynamics, and rebuild trust within the family system.
  • Eye Movement Desensitization and Reprocessing (EMDR) Therapy: EMDR is a structured therapy used to help individuals process traumatic memories and reduce their emotional impact.
  • Group Therapy: Group settings provide a non-judgmental environment where individuals can share experiences, gain insight, and reduce stigma.
  • Individual Therapy: This type of therapy offers one-on-one support, allowing people to explore personal goals, challenges, and triggers in a private setting.
  • Cognitive Behavioral Therapy (CBT): CBT helps identify and change unhelpful thought patterns and behaviors connected to substance use.
  • Dialectical Behavior Therapy (DBT): A type of CBT, DBT focuses on emotional regulation, distress tolerance, and mindfulness.
  • Medication-assisted Treatment (MAT): MAT combines therapy with approved medications to help reduce cravings and support recovery.

Addiction and Mental Health

Substance use disorder often occurs alongside mental health conditions such as depression, anxiety, PTSD, or bipolar disorder. This is known as a dual diagnosis. When both conditions are present, they can influence each other extensively. Substance misuse may begin as a way to cope with emotional pain, which can worsen mental health symptoms. Integrated treatment that addresses both substance use and mental health at the same time leads to the most successful treatment outcomes and the best chance at sustainable sobriety.
