"In 2011, in 1,804 cases (2010: 1,517), 133,650 cannabis plants (2010: 101,549) were seized (Table 10.6) which in both instances represents a market increase (+18.9% cases; +31.6% plants seized). The quantity seized thus reached the level of 2009 once more, the number of cases is the highest since 2003 (BKA 2012a). The increased number and quantity of plants seized as well as the doubling of the seized small plantations (see 10.2.2) imply on the one hand an increased (own) cultivation of cannabis in Germany and on the other, if one considers the increasing seizure numbers for marijuana and the falling numbers for hashish (see 10.3.1), an increased preference for marijuana and a diminished preference for hashish."
