There's two ways the psychiatric empire expands. 

One of them is pathologising or inventing disorders via the DSM and then treating people for several imaginary disorders.

The other avenue through which they expand is prescribing antipsychotics and antidepressants for all sorts of ailment 
such as olanzapine for sleep (they could be using benadryl or antihistamines, CBD and melatonin) as first line of treatment
but recently I remembered that there are anti-smoking pills and thought maybe they're antipsychotics. 

It seems that antidepressants such as Wellbrutin are prescribed to help people to smoke. Would people still take these pills
if they knew they can develop severe dependence and go through withdrawal horrors? Severe withdrawals affect about 25% of the
people who take psych drugs according to the only piece of research I ever found on the topic. It was a krager article. 

Has Wellbrutin be proven to be effective at getting people to stop smoking?
