Stimulant Addiction - Nicotine, Caffeine and other Stimulants
Ritalin is the trade name for methylphenidate and is made from methylphenidate hydrochloride which is an odorless, fine, white, crystalline powder. This stimulant type of drug works on the central nervous system and is far more potent than caffeine and similar to amphetamines. The neurological effects of Ritalin are very similar to those of cocaine as both create malfunctions within the brain.
Through the use of tobacco, nicotine is one of the most heavily abused addictive drugs and one of the the leading preventable causes of disease, disability, and death in the U.S. Cigarette smoking accounts for 90% of lung cancer cases in the U.S., and about 38,000 deaths per year can be attributed to secondhand smoke. Cigarettes and chew tobacco are illegal substances in most U.S. states for those under 18; a handful of states have raised the age to 19.
Smoking is a nasty habit that can be hard to break, even though most smokers know the risks associated with the use of tobacco products. Smoking addiction is defined as an unmanageable dependence on smoking tobacco. Quitting smoking often leads to uncomfortable physical, mental and emotional reactions. This is due to the fact that nicotine, the primary mood-altering chemical in tobacco products, is absorbed into the blood stream, crosses the blood-brain barrier, and binds to nicotine receptors in the brain leading to dependence. Nicotine is a psychoactive drug which stimulates the electrical activity of the brain. It is a central nervous system (CNS) stimulant, although smokers often experience a calming effect from tobacco use. Withdrawal effects begin when a smoker stops using nicotine. These can be very similar to withdrawal symptoms seen with other addictions.
