Quantitative measurement of active constituents has legal importance in narcotic drugs like Opium, Cocaine, Heroin etc. In marginal cases of quantitation, the uncertainty in measurement will have significant effect. On the basis of analysis, product has to be declared under NDPS act and also small or commercial quantities. Accurate quantitation is also required for reward to investigating agencies. Thus uncertainty in measurement with relation to true value of the contraband substance is very essential. In present study, an attempt has been made to quantify the contribution of systematic and random error for arriving at correct results for estimation of Diacetylmorphine in street sample of heroin.
