Yep, not a problem at all!

Yeah, the history of the chemical is really fascinating! It was even used as a performance enhancing substance at times...there's several famous instances of olympic athletes partaking in strychnine use.
As far as extracting it in a way that's not toxic the answer would objectively be yes...This is primarily because strychnine's toxicity (like all issues of toxicity) is essentially based upon the dosage used. Paracelsus is often described as the founder of toxicology, and he has a rather infamous statement that reads, "All things are poison, and nothing is without poison; only the dose permits something not to be poisonous." And that's pretty much exactly the case with strychnine. It can most definiely be extracted to small quantities where it is no longer toxic to ingest. And it was used historically in such a manner for quite a while. In fact, while there is no doubt that it is a powerdul substance....its toxicity level is quite the same as that of nicotine's (LD50 of 1–2 mg/kg in humans for strychnine, and an LD50 of 0.5–1.0 mg/kg for nicotine).
But yeah, herein lies the problem :D Some countries will still offer Nux-Vomica tinctures (Nux-vomica is the seed from which strychnine is extracted), lol but we're unfortunately not one of them. And this is the main safety issue with the substance...since there are no professional pharmaceutical grade tinctures of the substance, it forces those who might potentially be interested to consider doing an extraction themselves, which is HIGHLY dangerous.
Although all that is quite a shame. I've gotten proficient at the extraction and I really do find it to be somewhat of a wonder drug. Its my favorite stimulant (which is fascinating bc im not even really a huge fan of stimulants to begin with), it's my favorite nootropic, and it works wonders as far as the potentiation of psychedelics. But unfortunately, since this is a harm reduction site, I can't really say I recommend it bc the extraction process is definitely extremely dangerous...but I do hope that one day our society will develop a more open and objective view towards these substances, because if used in the correct manner and with the correct dosage they offer infinite amounts of potential.
