Ethanol hash oil (EHO)

Ethanol hash oil (EHO) refers to a potent cannabis extract made using food-grade ethanol alcohol as the solvent rather than hydrocarbons like butane or propane. Because ethanol is considered generally less toxic for human consumption and environmental exposure compared to other chemical solvents, it represents a safer solvent option for producing quality hash oil if handled responsibly. Ethanol is classified by the FDA as Generally Recognized as Safe (GRAS) for human ingestion when highly purified unlike butane and many other solvents. It also can be used to produce hash oil extracts through both cold and warm processes depending on preferences. Most importantly, properly purging out all traces of residual ethanol after extraction is absolutely critical for purity and consumer safety. When done with care at optimal temperatures by a practiced extractor, high quality EHO with comparable potency and aromatic flavors to other solvent-based concentrates can be achieved without some of the risks posed by hydrocarbons.
