"Methamphetamine should be administered at the lowest effective dosage"

"For treatment of children 6 years or older with a behavioral syndrome characterized by moderate to severe distractibility, short attention span, hyperactivity, emotional lability and impulsivity"

I am not opposed to the treatment of ADHD, and I understand the difference in purity between prescription amphetamines and street drugs, and the difference in effect from treatment dosage vs recreational use, but.. even so, it's a little hilarious to read, given my preconceptions regarding the drug.

Addicts who start on a street drug aren't typically in the habit of going to the doctor for their fix.

Some tidbits: Methamphetamine use has a high association with depression and suicide as well as serious heart disease, amphetamine psychosis, anxiety, and violent behaviors. Methamphetamine also has a very high addiction risk.[12] Unlike cocaine and amphetamine, methamphetamine is directly neurotoxic to midbrain dopamine neurons.[27] Moreover, methamphetamine use is associated with an increased risk of Parkinson's disease due to the fact that uncontrolled dopamine effluxion is neurotoxic.[11][28] Long-term dopamine upregulation occurring as a result of methamphetamine abuse can also cause neurotoxicity, which is believed to be responsible for causing persisting cognitive deficits, such as memory loss, impaired attention, and decreased executive function. Similar to the neurotoxic effects on the dopamine system, methamphetamine can also result in neurotoxicity to serotonergic neurons.[29]

(yes, I just coined a neologism. You can thank me later.)
