      • Conventional drugs are good in reducing positive symptoms but not negative symptoms

      • Quick and easy to take unlike CBT which takes a lot of time and only works it the patient wants it to and is motivated

        • Does not get to the root cause
      • Around 30% do not respond to antipsychotic drugs
        • They don't work for everybody
