Coke~ No doubt this is a fun drug under the right circumstances but like youve heard it is completly over rated..the high is no where near 15/20 minutes for me at least, its not even 5 before i start feinin for another line...I quit doin it because it started havin reverse effects with me after awhile i dunno why, and my nose took a big toll... pretty much a waste of time and $ unless its on someone else...
