Welcome Precip,you will find loads of info about CWE on Bluelight and info about practically every type of substance you can think of.
Plenty of very good folk on here.
Welcome to Bluelight Precipitator, there should be threads concerning CWE in both the Other Drugs and Basic Drug Discussion forums.
I am quite an experienced CWE'er myself, although my experience lies with using OTC codeine containing products the principle is exactly the same. If you have any questions regarding CWE or Bluelight in general then feel free to send me a PM and I will respond when I can.
