A new apparatus and method were devised for simple discrimination of hashish (Cannabis sativa L.) at the field, developed by the Office of Narcotics Control. The apparatus consists of two small fountain pen-sized glass cylinders ; the first solution is a chloroform suspension of a minute amount of Echtblausalz B and the second is a dilute aqueous solution of sodium hydroxide. A small amount of a sample is placed in the first solution, shaken for 1 minute, the second solution is layer over the first, and then mixed after 30 seconds. When the two liquids separate and the lower layer (chloroform layer) colors red, then the presence of hashish is suggested. If the chloroform layer does not color red, presence of hashish can be denied. Approximately 900 samples have been tested by this way to date and a good result was obtained, there being no case in which its result was contrary to the result of existing method of evaluation.
