Although cocaine and psychostimulant dependence are thought to be related to increased dopamine release, research from Tokyo and Long Island finds that the effect of antipsychotics did not differ from that of a placebo in regard to cocaine, amphetamine and methamphetamine use, addiction, craving, depression, anxiety, or abstinence. Antipsychotics were discontinued more than placebo, as a result of intolerability, leading to antipsychotics being outperformed by placebo in some measures.
How many millions did they spend to figure out drugs that make people feel like tired zombies won’t make them not crave stimulants ?
Can I have a million dollars to see if dry hot weather prevents people from getting thirsty ???
If you take antidopaminergics, you need/want more dopamine.
If you need/want dopamine, you take stimulants.
This could be the same with nicotine.
(Of course this is VERY simplified but why nobody cares it this time?)
