How do drugs affect the body systems depends on each system and each drug. The effects associated with drugs can vary from person to person. How a drug affects an individual is dependent on a variety of factors including body size, general health, the amount and strength of the drug, and whether any other drugs are in the system at the same time. It is important to remember that illegal drugs are not controlled substances, and therefore the quality and strength may differ from one batch to another.

Drugs can have short-term and long-term effects. These effects can be physical and psychological and can include dependency and addiction. You may act differently, feel differently, and think differently if you have taken drugs. And you may struggle to control your actions and thoughts.

You might begin to use drugs without thinking about any harm to your body. You might think drugs won’t become a problem because you are only a casual user. The more you take a drug, the more likely you will build up a tolerance to its effects. This can lead to the need to take larger doses to obtain the effects of the drug. For this reason, evidence suggests that after prolonged use, many drugs can cause dependence.

Drug dependence can quickly begin to affect your psychological and physical health and affect your work and social life. It is important to remember that there is no safe level of drug use. Be careful when taking any kind of drug.

How Do Drugs Affect The Body Systems? Different drugs, different effects

Drugs affect your body’s central nervous system. They affect how you think, feel, and behave. The three main types are depressants, hallucinogens, and stimulants:

  • Depressants slow or ‘depress’ the function of the central nervous system. They slow the messages going to and from your brain. In small quantities depressants can cause a person to feel relaxed and less inhibited. In large amounts they may cause vomiting, unconsciousness and death. Depressants affect your concentration and coordination, and slow your ability to respond to situations. It is important to not operate heavy machinery while taking depressants. Alcohol, cannabis, GHB, opiates (heroin, morphine, codeine) and benzodiazepines (minor tranquillisers) are examples of depressants.
  • Hallucinogens distort your sense of reality. You may see or hear things that are not really there, or see things in a distorted way. Other effects can include emotional and psychological euphoria, jaw clenching, panic, paranoia, gastric upset and nausea. Ketamine, LSD, PCP, ‘magic mushrooms’ and cannabis are examples of hallucinogens.
  • Stimulants speed or ‘stimulate’ the central nervous system. They speed up messaging to and from the brain, making you feel more alert and confident. This can cause increased heart rate, blood pressure and body temperature, reduced appetite, agitation and sleeplessness. In large amounts stimulants may cause anxiety, panic, seizures, stomach cramps and paranoia. Caffeine, nicotine, amphetamines (speed and Ice), cocaine and ecstasy (MDMA) are examples of stimulants.

The effects of a drug, and how long they last, depend on a number of factors

  • How you ingest the drug (by inhalation, by injection or orally). Compared with swallowing a drug, inhalation and injection are more likely to lead to overdose and dependence. If you are injecting drugs, sharing injecting equipment will increase your risk of contracting serious diseases such as hepatitis and HIV. It will also increase your risk of serious infection
  • Your mental health, mood and environment (that is, whether you are in a secure, happy place or an unsafe place) can affect the experience you have when taking drugs. If you have a mental health condition, drugs may exacerbate or complicate the symptoms of that condition
  • Whether you mix drugs, including alcohol. In particular, alcohol use may lead to high risk behaviour (such as drink driving) which can result in the serious injury or death of yourself or others.
  • The type and strength of drugs that you use
  • How the drug was made — substances manufactured in home labs may contain bacteria, dangerous chemicals and other unsafe substances, and have an unknown strength. Even one dose may cause an overdose that leads to brain damage or death
  • Your physical characteristics (including height, weight, age, body fat and metabolism)
  • The dose that you take
  • How often and for how long you have been using drugs

How Do Drugs Affect The Body Systems? Therapies For Drug Addiction & Programs

Therapy for drug addiction commonly consists of a combination of group and individual therapy sessions that focus on teaching those in recovery the skills needed to get and stay sober as well as how to navigate various situations without turning to drugs or alcohol.

However, it is necessary to note that there’s not a generic therapy that is the ‘best’ for everyone. Every person suffering from substance abuse disorder needs to find the Best Therapy For Drug Addiction that suits their own individual needs. 

Under the authority of the National Institute on Drug Abuse, Behavioral treatment is perhaps the most commonly utilized type of therapy for drug addiction that is frequently used during substance rehabilitation. Behavioral approaches help engage people in drug abuse treatment, provide incentives for them to remain abstinent, modify their attitudes and behaviors related to drug abuse, and increase their life skills to handle stressful circumstances and environmental cues that may trigger intense craving for drugs and prompt another cycle of compulsive abuse.

A general behavioral therapeutic approach has been adapted into a variety of effective techniques. These include:

How Do Drugs Affect The Body Systems? CBT can be applied as therapy for drug addiction in many different types of problematic substance use. People treated with CBT techniques learn to recognize and change their maladaptive behaviors.

How Do Drugs Affect The Body Systems? Therapy For Drug Addiction: Cognitive Behavioral Therapy (CBT) 

CBT can be applied as therapy for drug addiction in many different types of problematic substance use. People treated with CBT techniques learn to recognize and change their maladaptive behaviors. CBT can help people with coping skills, identifying risky situations and what to do about them, and preventing relapse. This approach is helpful because it can be paired with other techniques. The skills learned through CBT continue to be of benefit long after the initial therapy, and it can be used to treat co-occurring mental or physical health disorders as well.

How Do Drugs Affect The Body Systems? Therapy For Drug Addiction: Contingency Management (CM)

CM may also be effective in treating several types of substance use disorder—for example, alcohol, opioids, marijuana, and stimulants—and is used to encourage or reinforce sobriety. This drug addiction treatment method provides material rewards as motivation for desirable behaviors, such as maintaining sobriety. A major benefit of CM is that it can result in a reduction in the two of the biggest treatment-related issues: dropping out and relapse.

How Do Drugs Affect The Body Systems? Therapy For Drug Addiction: Motivational Interviewing (MI)

MI is a drug addiction treatment method of resolving ambivalence in recovering individuals to allow them to embrace their treatment efforts to best change their problematic substance use behavior. One benefit of MI is that, despite being facilitated by a therapist, those in recovery develop their own motivation and a plan for change over the course of several sessions, which can provide them with more of a sense of control over the course of their treatment.

How Do Drugs Affect The Body Systems? Therapy For Drug Addiction: Dialectical Behavioral Therapy (DBT) 

DBT can be adapted for many substance abuse cases, but mainly focuses on treating severe personality disorders, such as borderline personality disorder.

How Do Drugs Affect The Body Systems? Therapy For Drug Addiction: Rational Emotive Behavior Therapy (REBT)

REBT helps patients understand their own thoughts and then helps to develop better habits and thinking in more positive and rational ways and gain healthier emotions. The basis for REBT is the idea that rational thinking comes from within; external situations are not what give one the feeling of happiness or unhappiness.

How Do Drugs Affect The Body Systems? Therapy For Drug Addiction: Matrix Model
