For the mystery "natural flavours," mass spectrometry was used. He got the essential oils and their quantities down: lemon oil, lime oil, tea tree oil, cinnamon oil, nutmeg oil, orange oil, coriander oil, and a natural pine–like flavour called fenchol.

Was still missing coca. Then he realised they were basically tea leaves and the mystery flavour was actually tannins, which are non-volatile, so using mass spectrometry tannins won't show up. He found wine tannins are commercially sold in a water–soluble powder form, and this was the key pretty much.

This mix then had to be heated to blend/mature the essential oils, and then left to sit for 24 hours before being used in the final recipe to exact match the flavour profile.

For the past 2 years I've been using concentrates via 510 carts in Canada, unscented/no flavour additives. Before that I used a dry vape with cheaper pre-ground flower, but short battery life and maintenance got annoying plus dosage control is worse. Smoked before legalisation.

Sorry I should have quantified that younger than 30 to me was my childhood lol. I didn't clean up until I had kids.
