I’ve been performing some internet searches that could cause red flags in the office, but on the other hand it’s a story of citizen science and lab safety. There is a growing trend for people to perform solvent extractions at home, but what they’re extracting is tetrahydocannabinol, the active ingredient in marijuana, and they’re using highly flammable butane or isopropyl alcohol for the extraction.

Now there’s a bit of me that’s quite admiring of these home grown chemists, methodologies are available online and improvements are shared. However, in my experience, the venn diagram of people who are strongly pro-pot and people who are anti ‘scary chemicals’ has a pretty large central cross over. That leads to a lot of discussion about how smoking ‘hash oil’, the resinous product of these home extractions, is ‘more pure’. I’m not sure I agree, it’s still a mixture of compounds rather than pure THC, and despite claims of the oil being 90% THC by these home extractors, my survey of the literature suggests something topping out at 65%. And what about the additives in the solvent itself? But I’m not here to niggle over how good these extractions are, rather to make a point about how a little knowledge can be a dangerous thing.
