je hebt gelijk, speed is meth-amphetamine en ritalin methylphenidate.
Ritalin (methylphenidate) does contain an amphetamine-like backbone, however it is more complex. Take a look at the difference in Chem-Compare. The additional structures on this molecule also alter its interaction with the body and the neurons in our brains. Methylphenidate is reported to have less euphoric effects (some people describe it as 'more dull') than methamphetamine, but every individual is unique in their reaction to psychoactives, so no statement is universally true. While similar in backbone structure, amphetamine, methamphetamine, and ritalin are all quite unique drugs, with somewhat similar, but distinct, effects.
Another thing to note when talking about the differences in the amphetamine-class stimulants is that one of the strange effects of current culture is that particular drugs are demonized in the news, entertainment media, government information, and school curricula. Methamphetamine is particularly demonized, amphetamine somewhat less so, even though amphetamine-related stimulant drugs -- including methylphenidate (Ritalin), amphetamine (Adderall, Dexedrine), & methamphetamine (Desoxyn) -- are commonly prescribed for children from as young as age 3. All three of these can lead to difficult-to-break habits and can become a problem for some people who try them. But the marketing teams of the pharmaceutical companies do what they can to soothe parents' concerns by separating the image of street-speed users from the clean, clinical, healthy use of their products.
