I would say that on an industrial scale they could make it cheaper and safer than some tweeker making it from that list of ingredients in the trailer next to regular citizens.
The black market is more expensive b/c of the risk at every level.
Sure, they could make the manufacturing process cheaper/safer but that isn't my concern. My concern is that you then generate a large segment of the population who not only have a raging addiction but also begin to show paranoid schizophrenic tendencies which DO NOT go away with discontinuation of use.
The need for speed: an update on methamphetamine addiction
One of the most prominent effects of MA abuse on cognitive function pertains to the development of drug-related psychosis. Aside from the sudden psychosis-inducing effects of high doses of MA, prior exposure to MA, following metabolism and excretion of the drug, can also lead to an enduring form of psychosis. Studies conducted in Japan, where high levels of MA use have been prevalent for decades, report that between 36% and 64% of MA users who have experienced psychotic symptoms continue to present with these symptoms for more than 10 days after the cessation of MA use, even though the MA is eliminated from the blood stream in less than 5 days.53 Another study investigating female inmates in Japan observed that 21% of those having experienced MA psychosis remained in a psychotic state for more than 6 months, whereas 49% returned to their premorbid state but experienced “flashbacks” (i.e., spontaneous recurrence of psychotic symptoms that would fit criteria for a paranoid-schizophrenia psychotic relapse) during their 15–20 months of incarceration.53 Studies in Japan show that MA users with MA psychosis are much more likely to experience psychotic symptoms again if they use MA and are also more likely to have a psychotic relapse when confronted with stressful situations, even years after cessation of MA use.53
I don't know if you have ever had to deal with such people, but they scare the crap out of me and have a propensity for violence and aggression which is really unmatched.
