Note: that if you are using flower of the female plant you will find an end product with at least 5 times the strength of the oil produced using the leaf of the plant. The reason for this is:

The leaf contains a low percent of the active compound tetrahydrocannabinol (THC).Which upon extraction from the plant will be mixed with a larger percent of the compound cannabidol (which the cannabis plant converts into the more active isomer tetrahydracannabinol by means of natural acids within the plant itself). So, by the process of isomerazation (which I will give instructions for in a bit), we will help nature along by converting the cannabidol into THC.

Now when you do an extract from the flower of the female plant you get a larger percent of THC than you do cannabidol. Now the THC being good to begin with you also get a bonus. The THC that is present will be converted to delta-9-THC during izmerazation which has a more pronounced psychedelic effect than the regular isomer of THC. (you also get some ungodly head rushes.)

So in conclusion, upon extraction and izmerazation from the leaves / shake / sun-leaves of the cannabis plant you have a large percent of THC which you converted from the cannabidol and a small percent of the delta-9-THC isomer which was converted from the already existent THC that naturally occur in the leaves of the cannabis plant. Now since there is a high concentration of THC in the flowers of the female plant and a noticeably smaller amount of cannabidol, upon extraction and izmerazation of the flowers you get a low percentage of THC and a much higher percent of the delta-9-THC conversion. This leaves you with a more psychedelic product when all is said and done. A bit of technical information taken from the solvent FAQ on:

TETRAHYDROCANNABINOL (THC)
found in marijuana, the psychoactive stuff
prop: bp 200 C @ 0.02mm Hg (other cannabinoids may have bp's lower than 185 C)
sol: polar solvents, acetone, alcohol’s, etc.
note: this is an oily substance, not water soluble

Well it is time to get on with the extraction of tetrahydrocannabinol and the conversion processes.....

A LIST OF CHEMICALS THAT YOU WILL NEED:
