A coke fiend might also choose doing coke over spending time with their loved ones, looking after loved ones in times of need or missing prior commitments like work or appointments.
A coke fiend will usually spend all his/her money on cocaine when they get the chance and they will probably spend money on poor quality or imitation drugs rather than quit while they are ahead.
They will usualy be well into the early stages of adiction and crave it regularly even if they don't act on it.
Coke Fiend "Any of you guys wanna chip in for some coke?"
Friend 1 "I'm okay for coke dude. I've got beer and a bottle of tequila! You want a shot?"
Coke Fiend "No sweat bro, yeah I'll have a shot hit me up"
*Everyone is laughing and having fun doing shots and dancing*
Coke Fiend "So dude do wanna chip in for some coke"
Friend 2 "I don't have much cash bro so I don't know, maybe another night for sure, plus it's too late to get any good shit now"
Coke Fiend "Well how much do you have dude? I can ask Marko and Lisa if they can chip in and we can get a few bones, what do you say?"
*Starts to get awkward and kill the party vibe*
... and so on and so on.
