Someone who taking depressants is risking which of the following outcomes? appetite increase
heightened alertness
psychotic behavior
sleep disorders

The answer is "Psychotic behavior".

Psychotic disorders are a gathering of serious diseases that influence the psyche. They make it difficult for somebody to think obviously, make great decisions, react inwardly, impart adequately, comprehend reality, and carry on suitably.  

At the point when manifestations are extreme, individuals with psychotic disorders experience difficulty keeping in contact with the real world and frequently can't deal with day by day life. Be that as it may, even extreme maniacal scatters as a rule can be dealt with.
