Interesting little find on the Aus Insitute of Criminolgy site..
basically it shows you when people use certain drugs that can be found in the waste water of a sewage plant in QLD.
Anyway gotta run but definitely interesting, especially if into scat.

Table 2 indicates that the recorded levels of all drugs varied daily over the 12 days of sampling in 2009 and the 15 days in 2010. Increased quantities of methamphetamine, cocaine and ecstasy were detected on Saturdays and Sundays. As samples were collected at 6.00 am each day, this likely reflects consumption on Friday and Saturday nights. There were also notable changes in the levels of drugs identified in the two sampling periods. The average loading per 1,000 people of cocaine in 2009 (221mg, SD=100) was more than four times that seen in 2010 (52mg, SD=21); a significant decline—Kolmogorov-Smirnov Z=2.58, p<0.001. Conversely, loadings of methamphetamine increased between 2009 (158mg, SD=40) and 2010 (228mg, SD=40)—Kolmogorov-Smirnov Z=1.81, p=0.003. No changes were apparent in mean MDMA loadings between 2009 (131mg, SD=62) and 2010 (139mg, SD=125)—Kolmogorov-Smirnov Z=0.99, p=0.213. Daily loadings are displayed in Figure 1, which presents each drug type by each sampling year (mg/day/1,000 people).
