A major component of the illicit drug market can be subcategorized as the psychostimulant drug market, with cocaine and amphetamine as popular constituents. In The Netherlands, an increase in both health care outcomes addiction treatment and hospital admissions was noted for both amphetamine and cocaine throughout a period of 17 years (1992-2008). Both cocaine price and quality showed a decrease in The Netherlands during the studied period. We used time-series regression analysis to investigate whether price or quality of the drugs were associated with health care outcomes. Drug seizures were also added to the time-series regressions in order to check for possible effects of drug availability and supply. Price and quality of cocaine were strongly associated with health care outcomes of addiction treatment and hospital admissions. Price of amphetamine also showed a decrease during these 17 years, but was associated with an increase in addiction treatment only. Other amphetamine market variables did not show any relationship with the health care outcomes. It could be stated that following basic market logics does not apply equally to all psychostimulants of abuse. Other factors might play a role, such as the addictiveness or desirability of a specific drug in question. This finding is supportive of the dynamics of the illicit psychostimulant market affecting actual use and thereby health care outcomes.
非法毒品市场的一个主要组成部分可以细分为苯丙胺类兴奋剂毒品市场，其中可卡因和安非他命是常见的成分。在荷兰，17 年间（1992 年至 2008 年），安非他命和可卡因的医疗保健结果（成瘾治疗和住院）都有所增加。在研究期间，荷兰可卡因的价格和质量都有所下降。我们使用时间序列回归分析来研究毒品的价格或质量是否与医疗保健结果有关。还将毒品缉获量添加到时间序列回归中，以检查毒品供应和供应可能产生的影响。可卡因的价格和质量与成瘾治疗和住院的医疗保健结果密切相关。在这 17 年期间，安非他命的价格也有所下降，但仅与成瘾治疗的增加有关。其他安非他命市场变量与医疗保健结果没有任何关系。可以说，遵循基本的市场逻辑并不适用于所有滥用的苯丙胺类兴奋剂。可能还有其他因素在起作用，例如某种特定药物的成瘾性或吸引力。这一发现支持了非法苯丙胺类兴奋剂市场的动态影响实际使用从而影响医疗保健结果。
