the chances of making one paranoid schizophrenic are very low
Meth shows a 14% rate of chronic psychosis with evidence of permanent organic brain damage even among those who use it orally, although this only holds true for chronic use. I hardly think 14% is low. As for hair loss, my nephew took ritalin and his hair started falling at age 12. Idiossyncratic response? Maybe, but losing hair at 12 is not normal especially cosidering that his father and both grandfathers never went bald - and even if you have a bald father and bald grandfathers, losing hair a 12 is still not normal.
, hair loss is low, and you are comparing meth addicts, not people using threapeutic doses for add.
With dexamphetamine it's low when taken orally, yes, but meth is harsher on the scalpel although it's milder on the CNS - I mean in terms of side effects, not in pharmacodynamics at which meth is twice more active on the CNS than amphetamine.
they are all phenyethylamines,
Like I said, phentermine shares the phenylethylamine structure, but it's not pharmacologically classed as an amphetamine. An amphetaminic, yes, but not an amphetamine. The same is true for all psychostimulants that are not shedule II according to the DEA and do not have the phenylethylamine structure. The only compounds that satisfy both requirements are amphetamine, methamphetamine and perhaps phenmetrazine. Methylphenidate is a shedule II psychostimulant but it is not an amphetamine because it does not have the structure common to other amphetaminics, being a piperidine derivative.
have you taken phen phen before?
No, I've taken amphepramone(di-ethyl-propion), dexamphetamine and methylphenidate, and methylphenidate feels a lot more like dexamphetamine than amphepramone, even though amphepramone shares the phenylethylamine sructure of dexamphetamine whilst mehylhenidate doesen't. In terms of pharmacodynamics, metyhlphenidate is much closer to amphetamine than phentermine. Amphetamine and methylphenidate get you high; phentermine doesen't, which is why amphetamine and methylphenidate are both shedule II, whilst phentermine is shedule IV. Now, if you're talking about phenmetrazine, now that's a different story. Never took it, but a guy I know who was addicted to meth told me that directly mainliing it gets you as hgh as snorting meth. Anways, I don't take stimulants anymore due to the neurotoxic effect. While the direct neurotoxic effect of drugs like phentermine, methylphenidate and amphepramone is very low, they have some side neurotoxcity due to it's powerful vasoconstrictive effect: decreasing oxygen and blood supply to the brain is never good. As for meth, it is arguably the most neurotoxic drug known, even in low doses when taken orally. It's direcly toxic to the neurons of the substantia nigra area of the brain, due to excessive dopamine agonism.
