malachi,
Just an FYI. With the exception of maybe 10 times in the last five years, I haven't done coke that even comes close in comparison to all of the coke I got in the mid to late 80's and early 90's.
It's like its entirely differnt drug. The smell, taste, lack of drip, euphoria, and sexual desire tells me theres something amiss.
Your statement that anyone should be able to tell the difference between cocaine and ephedrine is absolutely correct. But bare in mind that if, without your knowledge, you have only tried ephedrine or cocaine cut with ephedrine, then you really wouldn't be able to tell the difference would you?
Plain and simply put, if only two lines of your suspected cocaine geek you out, make you uncomfortable, make it difficult to put sentences together and puts sex on the back burner, your not getting good cocaine at all. Chances are its either not at all, or cut with something like ephedrine which will completely deminish any of the good effects of the cocaine because it is an "active" cut.
