For many people struggling with addiction, the toughest step toward recovery is the very first one: recognizing that you have a problem and deciding to make a change. It’s normal to feel uncertain about whether you’re ready to make a change, or if you have what it takes to quit. If you’re addicted to a prescription drug, you may be concerned about how you’re going to find an alternate way to treat a medical condition. It’s okay to feel torn. Committing to sobriety involves changing many things, including:

The physician must state firmly, but empathically, that alcohol is a problem for the patient and that the patient determines the solution. Patients come for treatment through several means, often from a mixture of both coercion and concern. The clinician needs to understand the extent of resistance to effectively work with the patient. A good strategy is to learn about patients' goals and indicate discrepancies between their goals and their choices. Pointing out discrepancies is more effective initially than statements such as, "You have to quit," or, "You have to go to AA."
The specific medicines prescribed will vary depending upon your own particular experience of withdrawal and the symptoms you are manifesting, and it may be that certain medications will not be appropriate depending on your substance of abuse or your own personal health history; an experienced medical professional will be able to make those decisions to ensure you go through withdrawal as safely as possible.
Addiction is a chronic disease characterized by drug seeking and use that is compulsive, or difficult to control, despite harmful consequences. The initial decision to take drugs is voluntary for most people, but repeated drug use can lead to brain changes that challenge an addicted person’s self-control and interfere with their ability to resist intense urges to take drugs. These brain changes can be persistent, which is why drug addiction is considered a "relapsing" disease—people in recovery from drug use disorders are at increased risk for returning to drug use even after years of not taking the drug.

Upregulation of the cAMP signal transduction pathway in the locus coeruleus by CREB has been implicated as the mechanism responsible for certain aspects of opioid-induced physical dependence.[20] The temporal course of withdrawal correlates with LC firing, and administration of α2 agonists into the locus coeruleus leads to a decrease in LC firing and norepinephrine release during withdrawal. A possible mechanism involves upregulation of NMDA receptors, which is supported by the attenuation of withdraw by NMDA receptor antagonists.[21] Physical dependence on opioids has been observed to produce an elevation of extracellular glutamate, an increase in NMDA receptor subunits NR1 and NR2A, phosphorylated CaMKII, and c-fos. Expression of CaMKII and c-fos is attenuated by NMDA receptor antagonists, which is associated with blunted withdrawal in adult rats, but not neonatal rats[22] While acute administration of opioids decreases AMPA receptor expression and depresses both NMDA and non-NMDA excitatory postsynaptic potentials in the NAC, withdrawal involves a lowered threshold for LTP and an increase in spotaneous firing in the NAc.[23]

Naltrexone was approved by the FDA in 1994 for the treatment of alcoholism; however, it is currently prescribed for the treatment of opioid addiction. Sold in oral or injectable forms (ReVia and Vivitrol), naltrexone can help block the effects of opioids on the brain, making it less pleasurable to use these powerful drugs. Naltrexone is prescribed for opiate users who have been through the withdrawal phase and who are motivated to stick to a recovery program.
Cocaine is often viewed as an elite drug, associated with movie stars, models, and other celebrities; however, the destructive consequences of cocaine addiction are anything but glamorous. Produced from the leaves of the South American coca plant, cocaine can be snorted as a powder, or diluted with liquid and injected into the bloodstream. In the form of crack, cocaine can be smoked for an intensified rush of energy. As a central nervous system stimulant, cocaine accelerates the activities of the brain, nerves, and heart, putting even healthy users at risk of heart attack or stroke.

Stimulants, such as tobacco, cocaine or prescription amphetamines, stimulate the brain and nervous system, causing increased alertness. Depressants, such as barbiturates and benzodiazepines, slow activity in the brain and nervous system, causing relaxation. Hallucinogens, such as LSD and PCP, drastically disrupt the way the brain and nervous system communicate, causing hallucinations. Rehab: Last Week Tonight with John Oliver (HBO)
