Social - tired of being ripped

[s2them]

SWIM has bought cola multiple times and has been ripped. this last purchase was from a friend who gave SWIM a number, SWIM called this number he met him it was a very sketchy situation and he was a very shady man. he tells me to test so SWIM thinks this is going to be a good buy
no other dealers letSWIM test befor buying. so SWIM got a nice numb mouth and payed him.

When SWIM got home he snorted it and really didnt feel anything but a numb throat and a numb nostril. WTF is going on

the cola came in half rocks and half shake some of it looked like very shiny peices
he did the water test from a rock and it evaporated befor it hit he bottom
is coke liek weed and you dont feel the real effects the first couple of times
could you please help him and try to explain whats going on
