When Lacey visits Tys house

Ty is just being goofy. You’re supposed to lick the salt, drink the shot, then suck the lime. Ty snorts the salt and throws the shot over his shoulder mimicking the superstition over tossing salt over your shoulder reverses bad luck. The cocaine was snorted in between filming of scenes.

That would be a good question to ask the cast. I could see it going either way. I wouldn't put it past Ty to snort cocaine, and include it in his drinking game. And snorting salt would be nasty A.F.!
