Ritalin is the drug more commonly used for ADHD patients, compensating, among other functions, for a low volume of dopamine in the brain. Ritalin is, much like cocaine, a potent stimulant, and both of these substances look and function in pretty much the same way. Both produce a euphoric rush, elevating dopamine levels in the brain. The difference though is that Ritalin is not addictive, at least not when monitored by a doctor, and Ritalin comes in the form of a pill that one swallows, which gives it a slower trajectory to the brain. Because it is slow and does not flood the brain with instant dopamine, it is deemed relatively safe, although it is cheap and risks becoming a teenager’s favored drug in the U.S. In as much as methadone has been of help in combating the heroin addiction, it is hoped that Ritalin can do the same for cocaine.
