Medicines that could completely eliminate the desire to use drugs or even prevent the development of addiction, no.
But hospitals use special drugs to help patients get rid of the "breaking" and partly from addiction. Basically it is a combination of different antipsychotics, anxiolytics and hypnotics. Combining these different groups of drugs, doctors achieve good results in the treatment of "breaking." This is a standard old and quite productive approach to drug treatment.
The consequences of drug use are extremely harmful for the human body.
This is a high risk of HIV and hepatitis, severe infections (due to
lowered immunity), depression, up to suicide and mental illness
(schizophrenia). I'm not talking about a possible overdose, or the formation of physical dependence.
