MediKatie and I were very happy to get your comment - thank you! It's nice to know you're helping somebody. :)
Please ask any specific questions about the process you may have. It can actually be done a few different ways, and they can all be safe and effective. To be blunt with you, it is hard to do something wrong with cannabis as medicine, even in concentrated forms, even when working with solvents. If you can handle yourself in a kitchen, you can likely handle extracting cannabis oil. In my area, there are a lot of people extracting cannabinoids in various ways, 24/7. Oils, shatter, budder, tinctures, edibles, just about everything you can think of. Most of the dangers we associate with cannabis aren't real. Even overdosing on it usually means nothing more than having a long sleep. Maybe throwing up. Nobody gets hurt by cannabis and nobody dies. Almost no other therapeutic substance can say that! :)
