Dextroamphetamine is a psychostimulant drug which is known to produce increased wakefulness and focus in association with decreased fatigue and decreased appetite. Drugs with similar psychoactive properties can be referred to or described as "amphetamine analogues", "amphetamine-like", or having "amphetaminergic" effects. Enantiomerically pure dextroamphetamine is more potent than racemic amphetamine and has stimulant properties similar to racemic methamphetamine, though it is less potent and has not been shown to cause neurotoxicity, which is associated with methamphetamine use.

Right, and Wikipedia exactly proves my point! Ritalin != 'a more potent form of crystal meth'. Yes it's chemically related, and yes it has in the abstract and in people who do not have ADHD similar effects, but no it's not the same. H1N1 and seasonal flu are both influenza strains, except that one kills tens or hundreds of millions over a few years and the other one everyone gets once every few years and shrugs it off with a few days in bed. Does that mean that they're all the same?

In this case the weasel words are "has not been shown to" which of course is not the same as doesn't.
