DrugBuyers.Com: Ritalin

ritalin compare it's structure and effects to cocaine and amphetamines not MDMA which is partly a derivative of an amphetamine, but far from being similar to ritalin in structure or effect.

ritalin works by blocking the re-uptake of DOPAMINE while amphetamines release dopamine. So, there is similarity with ritalin and amphetamines in it's actions with dopamine.

On the other hand, MDMA has nothing to do with dopamine, but releases SEROTONIN.

let's compare the structure of MDMA to amphetamine at:

then compare the structure of amphetamine to ritalin at:

then compare the structure of ritalin to cocaine at:

http://www.erowid.org/cgi-bin/chem_compa...henidate_2d.gif

As you can see, ritalin has some structural properties of both amphetamine and cocaine, but less so with MDMA. No studies or scientists have ever said ritalin was more similar to MDMA than cocaine in any way.

Is meth the same thing as Amphetamines such as prescription drugs like adderall and ritalin?
A: "Meth" is meth-amphetamine, which is a type of amphetamine. The "meth" from Meth-amphetamine comes from the chemical name "methyl". The chemical Methamphetamine is composed of an amphetamine molecule with an additional methyl group attached to its nitrogen (amine group). A methyl is one of the simplest atomic groups which can be added to a molecule: it is a single carbon atom with a set of (usually) 3 hydrogens.

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.

Interestingly enough, many people described injected Ritalin as very similar to injected cocaine. "The effects of Ritalin, amphetamines and cocaine, including the side effects, are, in fact, indistinguishable... It should be known that experienced addicts are unable to distinguish injected cocaine from injected Ritalin or injected amphetamines."

Ritalin users face many safety concerns. Abuse or long-term use can cause heart problems and possible heart attacks in people with preexisting heart conditions. One prime example of this is the death of a 14 year old boy attributed to long-term Ritalin use.

- "The Certificate of Death under, due to, (or because of) reads: "Death caused from Long Term Use of Methylphenidate, (Ritalin)." "
