CANNABINOIDS
One plant, many different molecules.
Learn what researchers mean by THC, CBD, THCA, receptors, metabolism, and exposure before transferring a finding from one product to another.
What is THC? A research-first guide
How delta-9-tetrahydrocannabinol interacts with the body, what researchers measure, and where simple explanations fall short.
What is CBD? Claims, evidence, and approved medicine
CBD is not simply non-intoxicating THC. Its pharmacology, evidence, interactions, and regulation require their own explanation.
THCA vs. THC: chemistry before marketing
The acidic precursor and its decarboxylated product are related, but labels and legal shorthand often obscure the chemistry.
The endocannabinoid system, without the hype
Receptors, signaling molecules, enzymes, and the limits of the master-regulator metaphor.
THC half-life and detection windows are different questions
Impairment, blood concentration, metabolism, and a positive test follow different timelines, so no single countdown answers them all.
