Making RSO

Wrong polarity. Leaves behind chlorophyll in the process. RS mentions something like this in his tutorials. He suggests using a different solvent (can’t remember the name now) to vaporize the cholryphill out of the oil.
I believe Isopropyl alcohol (99% evaporates fastest) will be ok in terms of proper polarity as well.

Primary reason would be stripping chlorophyll with the ethanol. If using isopropyl, then it could be toxic if smoked.

I was looking on the tutorial "How to Make Medical Cannabis Extract Oil" where it is talking about RSO. It said very clearly:

My question is why the warning?

Is there a reason this RSO tutorial is for Edible Hash Oil?

I made RSO with 190 proof Everclear, thinned it out with wax reducer and it vapes very well. Great buzz!
