      <dc:description>Cannabis is the most widely used illicit drug in developed countries, and has a significant&#xd;
impact on mental and physical health in the general population. Although the evaluation&#xd;
of levels of substance use is difficult, a method such as the randomized response&#xd;
technique (RRT), which includes both a personal component and an assurance of&#xd;
confidentiality, provides a combination which can achieve a considerable degree of&#xd;
accuracy. Various RRT surveys have been conducted to measure the prevalence of drug&#xd;
use, but to date no studies have been made of the effectiveness of this approach in&#xd;
surveys with respect to quantitative variables related to drug use.&#xd;
This paper describes a probabilistic, stratified sample of 1146 university students asking&#xd;
sensitive quantitative questions about cannabis use in Spanish universities, conducted&#xd;
using the RRT.&#xd;
On comparing the results of the direct question (DQ) survey and those of the randomized&#xd;
response (RR) survey, we find that the number of cannabis cigarettes consumed during&#xd;
the past year (DQ: 3, RR: 17 aproximately), and the number of days when consumption&#xd;
took place (DQ: 1, RR: 7) are much higher with RRT.&#xd;
The advantages of RRT, reported previously and corroborated in our study, make it a&#xd;
useful method for investigating cannabis use.</dc:description>
