Cocaine Purity Test

The results of the test are shown in the picture. The test was done using a very, very pure sample of cocaine.  Here’s how we did it (from right to left):

• 2 mg cocaine ( 10 % purity)
• 5 mg cocaine ( 25 % purity)
• 10 mg cocaine ( 50 % purity)
• 15 mg cocaine ( 75 % purity)
• 20 mg cocaine. ( 95-100 % purity)
