datum from Europe and Australia showed similar trends , with decreasing price and increasing potency of drugs , according to thestudypublished Monday ( Sept. 30 ) in the daybook BMJ .
The lower prices and higher purity of these drugs suggest that the illegal drug supply has increased during the past two decades . At the same time , design of drug capture either increase or remained static .
