Ritalin makes kids act like lab rats - more compliant, more willing, and able to obey adult commands. Ritalin inhibits exploration, spontanaeity, and overall interest in the environment. It also induces repetitive, meaningless behaviours such as rhythmic head movements, pacing and chewing, picking or rubbing the body.
Over time ritalin will cause drug-induced brain malfunction.
Ritalin is most commonly used for making children obsessed with meaningless robotic activities.
