[Doping: health risks and relation to addictive behaviors].
The paper presents the health hazards of the major doping substances and raises some questions about the relationship between doping and addictive behavior.


OBJECTIVE
Current definitions of doping and addictive behavior are examined. The paper's goal is: 1- to assess the risks of neurotoxicity and overall toxicity of doping substances: stimulants, narcotics (seldom used as doping substances), and hormones, and assess their addictive potential; 2- to present available data on drug-dependent patients with a record of early prolonged and intensive physical activity or athletic practice.


CONCLUSIONS
Some doping substances present high risks for health at large doses, but usually low addictive potential and neurotoxicity. Dependency on doping substances and drift towards dependency to addictive drugs, if any, are therefore determined by genetic and environmental factors. A significant susceptibility to drug dependence has been observed in some cases of very intensive and competitive practice. Over-representation of intensive and competitive athletic antecedents among some drug-dependent patients could be accounted for in either of two ways. On the first account, the causal factor is a sensation-seeking character trait, with a likely genetic component, which predisposes the individual to the use of drugs or doping substances, as the opportunities arise. On the second account, the sudden interruption of intensive practice, and of the associated organic stress and hypersensitization of the hedonic pathway, creates a weaning syndrome and leads to the search for relief through drugs. Further exploration of this hypothesis is called for.
