"These crimes are related to offences committed in connection with commercial/professional dealing in narcotic drugs or smuggling of larger quantities of narcotic drugs. All drug dealing/trafficking crimes recorded by police are - just as consumption-related crimes - taken account of in this report irrespective of the outcome of later legal proceedings. Both in terms of proportion and absolute figures, cannabis played the most important role in drug dealing/trafficking crimes (30,765 crimes, 60.6% of all crimes; 2010: 29,306 crimes, 59.1%), followed at a large distance by heroin (4,980, 9.8 %; 2010: 6,403, 12.9 %; 2009: 7,205, 14.1 %) (Figure 9.1). Similar to heroin, the number and proportion of trafficking crimes related to cocaine (3,731, 7.6%; 2010: 3,763, 7.6%; 2009: 4,522, 8.9%) have slightly decreased in recent years. Since 2000, the proportion of trafficking crimes involving amphetamines has been on a continual rise and the case figure too slightly increased again after a slight decline in 2008 and 2009. In 2011, amphetamines accounted for 14.8% (7,497 crimes; 2010: 6372, 12.8%) of all dealing/trafficking crimes and thus overtook heroin for the first time, ranking third on this list (BMI 2012)."
