						What is the difference between depressant and anti-depressant?
I have referred to dictionaries and it seems  they are synonymous. 
Thanks.
					
				 
				
						
														
					
												"anti" is a prefix to a word that makes it opposite, for example:
social 
anti-social
But your words are a little different:
Alcohol is a depressant. (drug, sedative)
He took anti-depressant pills for two years. (to counteract depression)
											
					
				 
																									
						
														
					
												They are not synonymous.
depressant
adjective:  (chiefly of a drug) reducing functional or nervous activity.
noun: a depressant drug.
antidepressant or anti-depressant
adjective: (chiefly of a drug) used to alleviate depression.
noun:   an anti-depressant (or anti-depressant) drug.
											
					
				 
																									
						
														
					
													@tanguatlay,
												Depressants are not anti-depressants. .   
But often used as such.    
											
 
					
				 
																									
						
														
					
												A depressant drug reduces some bodily or nervous activity; an anti-depressant drug is used to treat an illness called depression.
