Chimps in an open-air forested enclosure have spotted veterinarian Raven Jackson carrying a caddy packed with their morning's juice treats and frozen bananas. A half-dozen dark-haired chimpanzees crowd the wire metal gate and wait for her to dispense the goodies.
Codeine is a narcotic. It is a pain reliever and a cough suppressant. Promethazine is an antihistamine. It blocks the effects of the naturally occurring chemical histamine in your body. The combination of codeine and promethazine is used to treat cold or allergy symptoms such as runny nose, sneezing, and cough.
From my experience, here are the reasons 'lean' or the pharmaceutical Promethazine w. Codeine has different colors. Just as different pharm. drugs such as Xanax come in different colors and shapes depending on the dosage. Purple is the strongest second, red then yellow blue and green. Supposedly there is a ''clear'' lean which is supposed to be the highest dose available.
