Warning - Do Not Use Near Explosive AtmospheresMaking extracts with solvents can be dangerous and even deadly. Depending on where you live, it may also be illegal. Unfortunately, there is no shortage of terrible information and advice on the Internet. Learning by watching YouTube videos or by trial and error is not something we recommend.

The best way to learn is from people who already know how to do it right (hint: if they don’t have a closed-loop extractor and a vacuum oven, they aren’t doing it right).

International Cannagraphic also has a very active extraction forum where many industry thought leaders share information. When it comes to Internet forums, however, it is important to remember that there’s always a mix of good and bad information and an investment in time is usually required to determine which is which.
