An analysis of drug samples received by the National Toxicology Institute at Madrid during the period from September 1985 to May 1987 was undertaken with a view to carrying out an epidemiological assessment of drug abuse. Of 414 street drug samples, 63.5 per cent contained heroin, 12.5 per cent cocaine, 8.5 per cent amphetamine and 15.4 per cent other substances. The concentration of heroin ranged from 21 to 60 per cent in most of the samples (91.8 per cent) that contained it. Similar concentrations of cocaine were found in the samples containing that substance. Adulterants were detected in 78.8 per cent of the samples containing heroin, 59.6 per cent of the samples containing cocaine and 56 per cent of the samples containing amphetamine. The most common adulterants in the samples containing heroin were caffeine (68.4 per cent), phenobarbital (19.7 per cent), methaqualone (13.4 per cent) and procaine (13.4 per cent), while lidocaine was the most common adulterant (52 per cent) in the samples containing cocaine.
为了对药物滥用情况进行流行病学评估，对马德里国家毒理学研究所于1985年9月至1987年5月期间收到的药物样本进行了分析。在414份街头毒品样本中，63.5%含有海洛因，12.5%含有可卡因，8.5%含有苯丙胺，15.4%含有其他物质。在大多数含有海洛因的样本（91.8%）中，海洛因浓度在21%至60%之间。在含有可卡因的样本中也发现了类似浓度的可卡因。在78.8%含有海洛因的样本、59.6%含有可卡因的样本和56%含有苯丙胺的样本中检测到了掺杂物。含有海洛因的样本中最常见的掺杂物是咖啡因（68.4%）、苯巴比妥（19.7%）、甲喹酮（13.4%）和普鲁卡因（13.4%），而利多卡因是含有可卡因的样本中最常见的掺杂物（52%）。
