Hot spots, dose arithmetic, homogeneity, residual solvent, titration and adulterants: the handling steps between an obtained compound and a dose, and the documented ways each one has killed people.

What this section is, and what it is not
Education and harm reduction. Not medical, legal or financial advice. Every factual claim carries a source; contested and single-source claims are marked as such on the page.
The boundary. This section teaches separation, purification, formulation, dosing arithmetic and analytical chemistry with real parameters, because withholding that detail from someone who will proceed anyway is the harm this library exists to prevent. It does not publish preparative routes for converting one cannabinoid into a more intoxicating one; those are described structurally and cited to the literature, without procedures.

A potent compound spread unevenly across a carrier produces lethal variance inside a single batch: one portion carries several times the dose of another, the difference is invisible, and the user's own prior safe experience with the same material is actively misleading. This is the mechanism that did most of the killing in the synthetic-cannabinoid era, and the arithmetic behind it applies to any potent cannabinoid or novel compound today.

The working page: how to compute active per gram and per serving for any carrier, how to do volumetric dosing by dissolving a weighed mass in a known volume, and the resolution, accuracy and linearity limits that decide whether a number off a balance means anything. A milligram-scale compound handled with a kitchen scale is not being dosed; it is being guessed at.

Solution, suspension and dry blend are three different states with three different guarantees, and only a true solution has uniform concentration by definition. This page covers solubility as the hard constraint, wetting and penetration, geometric dilution, fat-phase distribution in edibles, settling over time, and how producers verify uniformity by multi-point sampling and an RSD specification instead of assuming it.

Any solvent used to extract a compound or to distribute it onto a carrier has to be removed, and the compendial framework for how much may remain is explicit: USP <467> and ICH Q3C sort solvents into three classes and set either a concentration limit or a permitted daily exposure. Inhalation is the hard case because there is no first pass, the delivery is alveolar, and heating opens a pyrolysis route that swallowing does not.

Start low and go slow is a pharmacokinetic argument, not a slogan: the safe re-dosing interval is set by the time to peak effect for the route, which is minutes for inhalation and hours for oral. It also has a hard limit — tolerance to a partial agonist does not transfer to a full agonist, and an unidentified compound cannot be titrated at all because there is no dose-response curve to titrate along.

The documented contamination record, not a list of fears: brodifacoum in synthetic-cannabinoid products causing an outbreak of coagulopathy, household and agricultural insecticides on smoked material, vitamin E acetate as the diluent behind the EVALI epidemic, and metals from hardware and catalysts. The principle that closes the page is that "it was sold as X" is not identification.
