Mos def not it's an atypical antidepressant with sedating effects due to it's anti-histaminergic action. Check wiki it's not a anti psychotic.Mirtazepine is an antidepressant/antipsychotic first and foremost.
The anta or inverse agonist action on the 5HT2a receptor is said to prevent a person from tripping on that class of psychedelics. As well as aborting a bad trip. No personal experience though.
And benzo's aren't rx-ed like in the states everywhere, still people cope.
If it wasn't for the taste thing I could have dropped a legal addicting herbal solution.
