Caffeine is a white crystalline xanthine alkaloid stimulant drug that acts as a stimulant drug. This bitter alkaloid is part of chemical mixtures found within insoluble complexes guaranine which is found in guarana, theine which is found in tea, as well as mateine which is found in yerba mate.

Caffeine is found in different quantities within leaves, beans, and even some fruit. For the most part humans use caffeine that has been extracted from cherries of the coffee plant as well as the leaves from the popular tea bush. Occasionally you can find caffeine as as source from the kola nut, guarana berries, Yaupon Holly, and yerba mate.

There is great debate regarding the pros and cons to caffeine, as well as it’s effects on the body. For starters caffeine is first and foremost a central nervous stimulant. Because of this caffeine can help to fight off drowsiness thus increasing the ability to focus needed attention. Some of the most popular drinks that contain caffeine are tea, coffee, energy drinks, and even the common soft drinks. Because of this these drinks are very popular among most all people. In fact caffeine is the most widely consumed psychoactive substance in the world. Here the debate often turns to the fact that caffeine is also not regulated in most parts of the world. Statistics show that more than 90% of North American adults consume caffeine on a daily basis.

The group that I would like to discuss regarding possible negative effects in particular is that of body builders and weightlifters. Caffeinated drinks are also very popular among this group. Besides possible nervousness, anxiety, tremulousness, insomnia, muscle twitching, respiratory alkalosis, stress, gastrointestinal problems, adrenal exhaustion, premature aging, headaches, and heart palpitations, caffeine can also be very constricting when it comes to blood flow and muscle growth, the very thing that a bodybuilder and weightlifter strive after. In fact caffeine limits blood flow and this is exactly what you don’t want. When the blood flow is restricted muscle growth is stunted. This is definitely the last thing that you could want if your goal is to grow your muscles.

For this reason it is suggested that when taking a muscle builder of any kind, such as a creatine, that you chose one without the stimulant caffeine. In fact there are many supplements that you can take to help build muscle that have no trace of stimulants like caffeine. Caffeinated muscle builders have been shown to reduce the benefits of different creatines and NO2 by constricting blood vessels. As a vessel constrictor it significantly decreases the ability to get the benefits of a lot of ingredients found in supplements. For example if you are taking caffeinated creatine, it will actually decrease the likelihood that the creatine will effective reach you targeted muscle group. Because of this it is extremely important that you don’t use any blood constricting supplements that contain caffeine.

Methylphenidate (MPH) is a central nervous system stimulant, which affects chemicals in the brain and nerves that contribute to hyperactivity and impulse control. Hence, this is used in the treatment of Attention-Deficit Hyperacitivity Disorder (ADHD), depression, lethargy, obesity, and other psychiatric disorders like obsessive-compulsive disorder.

Many people, particularly teens think that MPH is safe or mild drug because of its medical use. Pre-teens and adolescents abuse this drug to lose weight, stay awake or increase their attention span or for euphoric effects. According to a report by the National Institute on Drug Abuse (NIDA) released in 2009, 1.8 percent of 8th graders, 3.6 percent of 10th graders, and 2.1 percent of 12th graders abuse methylphenidate.

Many of them are ignorant of the adverse side effects of using methylphenidate in higher doses or without prescription. There are many common and serious side effects of MPH abuse. Some of them are:

Common side effects:
The few main common side effects of methylphenidate abuse are:

Addiction
According to the U.S. Department of Justice, MPH abuse may lead to tolerance and severe psychological dependence, Methlyphenidate is considered as a ‘Schedule II drug,’ as it has high addiction potential. Methylphenidate is as addictive as cocaine or any other illicit drug.

Anxiety and irritability
MPH abuser may feel restless, edgy or keyed up. MPH abuser will have difficulty in concentration, muscle tension, sleep disturbances which result in anxiety and irritability. MPH results in anxiety because of increase in blood pressure.

Decreased appetite
The MPH acts as an appetite suppressor. MPH abusers may experience fatigue as the proper nutrition is not supplied to the body due to decreased appetite. It also induces weight loss. This is the main reason of abuse in teenagers for weight reduction. This overall leads to malnutrition.

Headache and stomach ache
Many people using MPH without a professional medical practioner’s advice, suffer from headache and stomach ache. As with any other illicit drug, headache and stomach ache might result because of the methylphenidate drug overdose.

Other effects
The other effects of MPH include nausea, vomiting, dry mouth, growth suppression, leukopenia (decrease in WBC), hypersensitivity, skin rashes, anemia, jaundice, nervousness, anorexia, tachycardia, agitation, hallucinations, psychosis, hyperthermia, dysrhythmias, lethargy, hypertension etc.

Serious effects:
Some of the serious effects of MPH abuse include:

Slow growth (height and weight)
As the appetite is decreased by the use of MPH, proper minerals and vitamins which are required to the body are not provided. This results in slow growth. Usually, there will not be much increase in weight and height. Dwarfism might result as a result of malnutrition.

Seizures
Seizures are one of the major side effects of MPH. Generally, seizures are caused because of abnormal brain function. Methylphenidate drug abuse causes seizures as it affects the chemical composition of the brain. Prolonged use of MPH will lead to epilepsy.

Eyesight changes or Blurred vision
After the intake of MPH, some people have visual disturbances. MPH abuse causes changes in eyesight. Sometimes, it may also result in blurred vision as a result of overdose. The overdose might also result in enlargement of the pupil of the eye.

Many children and adults are getting addicted to this drug as a result of prolonged abuse. It is important to know the serious and adverse effects of this drug. It is necessary to educate people, particularly teenagers about the adverse effects of MPH in order to prevent them from destroying their life.
