To compare the progression of substance use milestones between cocaine- and cannabis-dependent patients.
Using data gathered from two separate clinical studies for treatment of cocaine dependence and cannabis dependence, 130 cannabis-dependent and 112 cocaine-dependent individuals were compared on milestones related to their substance use.
In cannabis- vs. cocaine-dependent patients, the mean age of first use, regular use and first treatment contact differed significantly. No statistically significant differences were found between the two groups for other measured milestones.
These results differ from most epidemiologic studies that suggest cocaine users progress more rapidly to regular use and treatment contact.
比较可卡因和大麻依赖患者物质使用里程碑的进展情况。
利用来自两个独立的可卡因和大麻依赖治疗临床研究的数据，对 130 名大麻依赖者和 112 名可卡因依赖者的物质使用相关里程碑进行比较。
与可卡因依赖者相比，大麻依赖者首次使用、规律使用和首次治疗接触的平均年龄差异有统计学意义。两组之间在其他测量的里程碑上没有发现统计学上的显著差异。
这些结果与大多数流行病学研究不同，后者表明可卡因使用者更快地进展到规律使用和治疗接触。
