Here's a 1980 clip showing mostly young people drinking at a house party and also at a bar. Several people are also smoking. 

A person pours wine from a bottle into a plastic cup. 

A bartender fills two large, clear glasses with beer from a tap. A wall is lined with bottles of hard liquor. 

A young white guy kisses a woman sitting at the bar -- perhaps a woman he just met. 

A man sitting at the bar and wearing spectacles takes a drag from his cigarette and exhales; smoke exits his mouth and nose. A middle-aged man takes a swig of beer while also holding a lit cigarette.
