Addiction is a complex and chronic condition characterized by an inability to control or consistently abstain from substance use in spite of all the harm it causes.1,2,3 In some cases, the road to addiction may start with intentional use of drugs and alcohol but, at some point, the person’s decision to continue using becomes increasingly out of their control.2,3,4 Eventually, seeking and consuming the drug/alcohol becomes a compulsion.2,3
It is common for both tolerance and physiological dependence to develop in those who compulsively or otherwise consistently use substances. As tolerance develops, a person begins to no longer experience the effects of a given drug or alcohol in the way they did before. Therefore, it takes a larger dose to achieve the same response as when used previously.4,5 As the frequency and amount of substance use increases to counter the effects of tolerance, the development of physical dependence may also be hastened. People with significant dependence will come to need alcohol or drugs to avoid the onset of withdrawal or, potentially, to be able to function normally in day-to-day life.4,5

The withdrawal syndromes associated with certain types of physical substance dependence can be markedly unpleasant and/or dangerous.4 People at risk of a severe or complicated withdrawal stand to benefit from the added supervision, monitoring, and, when required, medications able to be administered in a medical detox setting.2,7,8 Professional detoxification services are available to help you through distressing withdrawal symptoms, helping provide comfort and safety throughout the process.2
Addiction affects areas of the brain involved in reward and motivation, learning and memory, and control over behavior.1,2,3 Substance addiction does not develop as a function of choice; it is instead born from a complex interplay of many different factors, including genes, trauma, drug access, and community influences.1 In addition, different groups have unique issues that surround their individual addictions, and these people may benefit from tailored treatments that take into account culture, gender, age, and socioeconomic factors.6
The journey from a substance use disorder (SUD) to a healthy, sober life is not a quick and easy one. For many, it takes a lifelong commitment of dedication and hard work. The road toward sobriety may be difficult, but professional treatment helps many people start that endeavor.
