It's because of the abuse potential, stims are more tightly controlled than benzos in most places for various (not always strictly logical) reasons.

Illicit use
Some people abuse MPH by crushing the tablets and snorting them thus changing the typical theraputic delivery system. The "high" results from the rapid increased rate of dopamine transporter blockade due to quicker absorption into the bloodstream. When abused, the effect of Ritalin is similar to that of cocaine or amphetamine and such abuse can lead to addiction. When taken orally in prescribed doses, MPH has a low addiction liability and rarely produces a "high". Both the United States Drug Enforcement Administration (DEA) and the United Nations International Narcotics Control Board have expressed concern about the ease with which legally prescribed MPH is diverted to the illicit market.[33][34] According to the DEA, "The increased use of this substance [MPH] for the treatment of ADHD has paralleled an increase in its abuse among adolescents and young adults who crush these tablets and snort the powder to get high. Youngsters have little difficulty obtaining methylphenidate from classmates or friends who have been prescribed it."[35]
Volkow et al. (1995) found that the slow clearance of methylphenidate from the brain may discourage the repeated self-administration found in other addictions, reducing the addictive liability of methylphenidate.[36]
In some areas, particularly where other illicit stimulants such as amphetamines are not as common, methylphenidate is popular amongst intravenous drug users. While not all available tablets can be readily prepared for injection, the standard brand name Ritalin tablets can be dissolved easily in water, making them ideal for intravenous use. This can be quite dangerous, however, as many available methylphenidate tablets use talc as a filler. The intravenous injection of talc can result in serious health problems, particularly pulmonary granulomas, which can lead to pulmonary fibrosis and pulmonary hypertension. This often leads to problems breathing, and in some cases, death. [37]
A study conducted by the University of Michigan's Substance Abuse Research Found that in a survey of over 10,000 college students, up to 25% of them had used Ritalin non-medically. The demographic of these students also admitted they were more likely to smoke cigarettes and marijuana, as well as take cocaine, ecstacy, and other drugs.
Street names for Ritalin include: vernies, diet coke, kiddie cocaine, kiddie coke, vitamin R, R-ball, poor man's cocaine, rids, skittles, R-pop, baby blow, coke junior and smarties.
