Dexedrine is a prescription drug that is used to treat ADHD and narcolepsy and works by activating the reward system within the brain, especially when repeated use is done. Unfortunately, with the long-term use with the drug, the brain will no-long function properly without it unless the proper help is gotten. This is similar to all central nervous system stimulants, whether it is pharmaceutical or an illegal street drug. The long-term use of Dexedrine will cause a tolerance to develop, which will create physical and psychological dependencies causing an addiction. It is when the addiction develops that a person will tend to spiral out of control, some worse than others. When this happens, the family or friends should intervene, and get their loved ones the proper help. Within the state of Illinois are different outpatient and inpatient drug treatment centers and detox facilities to help addicts and their families. The rehabilitation process will be unique for each person, but prescription drug addiction does not have to be a life-long problem. Ritalin is often referred to as a 'smart drug' by those who use the drug recreationally, and this is like any other type of central nervous system stimulant, there is a misconception that it will improve a person's performance. Ritalin is a brand name for methylphenidate, which is a central nervous system stimulant, and Ritalin is the most commonly prescribed drug in the United States that treats ADHD and ADD. In fact, the United States consumes roughly 80% of the world's methylphenidate. When Ritalin is taken as prescribed, there will typically be no problems, it is only when the drug is misused or even taken longer than required where a person will develop a tolerance. A dependency on Ritalin can happen both physically and psychologically. The effects of Ritalin are similar to cocaine and amphetamines. Drug rehabilitation centers within the state of Illinois can offer services through both inpatient and outpatient facilities to help treat prescription drug addiction.
