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.
The pH of urine is between 5.8 and 7. It is slightly acidic to neutral. Infection is generally seen, when the pH levels are lesser than 5.5. Infection, in course of time, gives rise to alkaline urine with a pH of 7.5 or higher.Ascorbic acid is helpful in increasing the pH.he pH of the urine is an indicator of the pH of the blood. In certain conditions, such as renal tubular acidosis, it is the other way round. Urine is acidic in distal renal tubular acidosis, though the blood is alkaline. Foods that raise the urine's acidity are referred to as acid forming foods.
