High blood pressure is a health danger. 

A researcher wishes to study the effects of different drug treatments that will hopefully lower blood pressure.

They give their helpers 4 colors of pills: 20 white, 20 yellow, 20 red and 20 blue.  

They are told

• the white pills are 30 g doses of a new drug
• the yellow pills are 50g doses of the same new drug
• the red pills are 30 mg doses of an old drug
• the blue pills are 50 g does of the same old drug

The helpers give the patients the drugs and will measure their blood pressure later.

The patients do not know each other and never see each other's pills.
