"Sex, drugs, and rock 'n' roll: hypothesizing common mesolimbic activation as a function of reward gene polymorphisms". Journal of Psychoactive Drugs. 44 (1): 38–55. doi:10.1080/02791072.2012.662112. PMC 4040958. PMID 22641964. It has been found that deltaFosB gene in the NAc is critical for reinforcing effects of sexual reward. Pitchers and colleagues (2010) reported that sexual experience was shown to cause DeltaFosB accumulation in several limbic brain regions including the NAc, medial pre-frontal cortex, VTA, caudate, and putamen, but not the medial preoptic nucleus. Next, the induction of c-Fos, a downstream (repressed) target of DeltaFosB, was measured in sexually experienced and naive animals. The number of mating-induced c-Fos-IR cells was significantly decreased in sexually experienced animals compared to sexually naive controls. Finally, DeltaFosB levels and its activity in the NAc were manipulated using viral-mediated gene transfer to study its potential role in mediating sexual experience and experience-induced facilitation of sexual performance. Animals with DeltaFosB overexpression displayed enhanced facilitation of sexual performance with sexual experience relative to controls. In contrast, the expression of DeltaJunD, a dominant-negative binding partner of DeltaFosB, attenuated sexual experience-induced facilitation of sexual performance, and stunted long-term maintenance of facilitation compared to DeltaFosB overexpressing group. Together, these findings support a critical role for DeltaFosB expression in the NAc in the reinforcing effects of sexual behavior and sexual experience-induced facilitation of sexual performance. ... both drug addiction and sexual addiction represent pathological forms of neuroplasticity along with the emergence of aberrant behaviors involving a cascade of neurochemical changes mainly in the brain's rewarding circuitry.
Drug addiction is a condition that is characterised by repeatedly taking or administering drugs - whether these are illegal drugs such as heroin, cocaine, or MDMA/ecstasy, or legal prescription drugs - to the extent that you become both physically and psychologically dependent on these substances. Regardless of the type of drug addiction that you have developed, continued drug use can soon become a serious problem and can lead to a range of serious long-term consequences, and may even be fatal.
Drug addiction is a growing concern in the United States. People often use drugs as an outlet for their problems, although drug use creates its own problems over time. Drug addiction not only affects a person’s health and relationships, but also impacts society and the environment. There are numerous treatment options to guide people toward a sober and healthy life.
Getting alcohol out of the addicted person’s system is the first part of recovery. People with a severe alcohol addiction can experience intense withdrawal symptoms. A supervised alcohol detox is usually necessary for people addicted to alcohol to prevent potentially fatal complications. Shaking, sweating, seizures, and hallucinations are possible alcohol withdrawal symptoms. Alcohol Rehabilitation Centers - What is it like going to in Rehab

Drug dependence means that a person needs a drug to function normally. Abruptly stopping the drug leads to withdrawal symptoms.

As with other diseases and disorders, the likelihood of developing an addiction differs from person to person, and no single factor determines whether a person will become addicted to drugs. In general, the more risk factors a person has, the greater the chance that taking drugs will lead to drug use and addiction. Protective factors, on the other hand, reduce a person's risk. Risk and protective factors may be either environmental or biological.

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.
