Stimulant is defined as a substance that raises levels of physiological or nervous activity in the body. Medications such as Ritalin, Conceerta, Biphetamine, and Dexedrine are known stimulants that have dangerous, and sometimes fatal side effects including nausea and vomiting, a sense of euphoria (being high), paranoia, sweating, anxiety, mania, hyperventilation, loss of motor skills, loss of appetite, increased energy, insomnia, dilated pupils, cracked or dry lips, nose irritation, aggression, suicidal thoughts, panic, homicidal tendencies, hallucinations, intense fatigue, dehydration, irregular heartbeat, confusion, irrationality, dental damage, rough skin, impaired decision making skills, cardiovascular system failure, psychosis, convulsions, seizure, heart attack, chest pain, blurred vision, headache, panic attacks, weight loss, stomach pain, nervousness, vertigo, teeth grinding, jaw clenching, increased energy, distortions of perceptions, increased body temperature and blood pressure, sadness, decreased libido, cravings, and poor memory or concentration. Drugs such as cocaine, heroin, marijuana, alcohol, ecstasy, amphetamine, methamphetamine, and cocaine are known stimulants that have terrible effects on both the body and the mind. Of course, not all stimulants, as long as they are taken in the correct dosage, are bad for the body. Some stimulant medications are used to treat ADHD, providing people with better attention spans and concentration skills. According to WebMD, stimulants aren’t habit-forming in the doses used to treat ADHD in children and teens and there is no evidence that taking them leads to drug abuse. In fact, studies have shown that people with ADHD who are treated with medication have lower rates of substance abuse than people with ADHD who are not treated. There are many stimulants available to treat ADHD such as short acting, intermediate-acting, and long-acting forms. The short-acting forms are usually taken two or three times a day, and the long-acting ones just once a day. The benefit of short-acting is that the patient has more control over when they have medication in their system. The downside is that they have to remember to take them regularly. Some kids and teens who take stimulants grow slower than those who don’t, but ultimately it doesn’t affect their final height. Side effects of the stimulants used in ADHD medication are headache, upset stomach, and higher blood pressure, however, they often go away after a few weeks of taking the medication because the body eventually adjusts to the influx of chemicals within the body. Other, rarer, side effects include loss of appetite, weight loss, nervousness, insomnia, and muscle spasms. Of course, because ADHD affects each person different, not everyone should take stimulants. For example, those with glaucoma, severe anxiety, tension, agitation or nervousness, muscle spasms, pregnant, have a liver or kidney disease, high blood pressure, seizures, depressed, have a history of alcohol or substance abuse, heart disease, Tourette’s syndrome, history of psychosis or are currently psychotic, or are on any other type of stimulant should not take stimulants without direct instruction from a doctor or medical professional. Taking stimulants with these conditions may result in the conditions worsening which may result in detrimental mental and physical side effects.
