cold water extraction

[jay]

This is my first post as a new member and iam thirsty for knowledge.Any help is realy appreciated.

1-My experience is limited to cold water extraction but the caffiene is very limiting.Any suggestion on removing or reducing the caffiene is appreciated.The simpler the better.

2-Is codiene obtained by cold water extraction smokable or does it have to be changed to base.

3-I have read a lot on the internet about different chemical extractions/seperations using chloroform among other chemicals.It is immposible for me to obtain chloroform so i thought i can make it and from reading i understood that chloroform can be made by reaction of ethanol with chlorine through distilation can anybody provide more precise information on that.Or maybe somebody can give me an obtainable substitute.
