The ADAPT software system was used to create models for the prediction of gas chromatographic relative retention times (RRTs) of stimulants and narcotics that are analyzed in doping control of athletes. The two main methods that were followed for building the models were the quantitative structure-retention relationship (QSRR) and multiple linear regression analysis. The main proposed model for the entire data set had a multiple correlation coefficient R = 0.991 and standard error s = 0.046 or approximately 4.5%. Because of the relatively high standard error of the main model, a second model was built on a subset of compounds with R = 0.982 and s = 0.027 or approximately 2.5%.

Does the media fan fake panics, forecast possible issues, create real problems, or detect problems at an earlier stage than treatment resources? A study of the relationship of tabloid news coverage of MDMA (Ecstasy) to drug treatment service demand found that treatment agencies were more concerned about amphetamine use but conversely tabloid coverage centred on ecstasy. Casual enquiries to a few drug agencies one year later discovered reports of increased numbers of clients presenting for ecstasy and reports of the drug's increased availability. The relationship between media coverage and changing drug availability and drug use is unclear. Short-term studies are unreliable, and interpretation of the relationship between drug use and media coverage runs a permanent risk of generating contradictory conclusions. The need for long-term serious study of the relationship between the media and drug use is stressed.
