i just began a thread about coke. i just bought some for the first time tonight and railed three conservative lines. i felt a little europhoric, talkative, and a hint of anxiousness, but nothing real bad. the drip made my throat kind of numb, i think that caused me to think i was having trouble breathing. it has a "chemical" odor. can anyone give me tips on the use of this, so i dont' kill myself and tell me how i can know if the coke is any good?????????????????? thanks in advance for any tips on this. i am alone and purchased a gram of this stuff.
