9 Studies of adult users of cocaine and heroin have found that youth use of marijuana correlates strongly with later use of cocaine and heroin. Children agedtwelve to seventeen who use marijuana are eighty-five times more likely to use cocaine than children of the same age who have never used those substances.
Urine pH. Urine pH is used to classify urine as either a dilute acid or base solution. Seven is the point of neutrality on the pH scale. The lower the pH, the greater the acidity of a solution; the higher the pH, the greater the alkalinity.ecretion of an acid or alkaline urine by the kidneys is one of the most important mechanisms the body uses to maintain a constant body pH. A highly acidic urine pH occurs in: 1  Acidosis. 2  Uncontrolled diabetes.
Urine, like other body fluids, can be either acidic or alkaline. Acidic substances have a pH of less than 7 and alkaline substances have a higher pH. Urine normally is slightly acid, with a pH around 6, although it can range from 4.5 to 8. Urine pH changes, depending on your diet, certain disease processes and the medications you take. Excreting acid or alkaline urine helps maintain the body's acid-base balance, the balance between acidity and alkalinity. What you eat can alter the pH of your urine, although it doesn't change the pH of your blood. Vegetarians generally have more alkaline urine than meat eaters, because meat and dairy produce acidic urine and most vegetables and fruits a more alkaline urine.
