Methamphetamine causes a release of high levels of dopamine into the areas of the brain that have to do with the feeling of pleasure and reward, which is why the drug is so addictive.
Women who consume in excess of one alcoholic drink per day increase their risk for motor vehicle crashes.
Drug or alcohol withdrawal symptoms may be even more dramatic when these substances have masked prolonged malnutrition, disease, chronic pain, or sleep deprivation.
Serious side effects as a result of methamphetamine use which could be life threatening can include convulsions, dangerously high body temperature, stroke, cardiac arrhythmia, stomach cramps and shaking.
