Cannabis Fundamentals
What Is Cannabis?
Cannabis is a plant genus that includes psychoactive and non-psychoactive varieties used for medical, adult-use, and industrial purposes.
What Is Hemp?
Hemp is legally defined cannabis with low delta-9 THC concentration, often used for fiber, grain, cannabinoids, and extracts.
Cannabis History
Cannabis has been used for medicine, fiber, ritual, and trade for thousands of years before modern criminalization and legalization waves.
Medical Cannabis History
Medical cannabis history spans traditional medicine, long research interruptions under prohibition, and state-level modern medical programs.
Cannabis Prohibition
Cannabis prohibition created legal, social, and research constraints that still shape enforcement, public health, and market access outcomes.
Modern Legalization
Modern legalization is a patchwork of state and national models balancing public health, tax revenue, justice reform, and business regulation.
Cannabinoids
THC
THC is the primary psychoactive cannabinoid associated with cannabis intoxication and many therapeutic research discussions.
CBD
CBD is a non-intoxicating cannabinoid widely discussed for wellness and medical applications, with mixed evidence depending on use case.
CBG
CBG is often described as a precursor cannabinoid and is under active research for potential anti-inflammatory and neurobiological relevance.
CBN
CBN is a minor cannabinoid associated with ongoing research around sleep, sedation, and product-aging chemistry.
CBC
CBC is a lesser-known cannabinoid under investigation for inflammation, pain pathways, and possible synergistic effects.
THCV
THCV is a cannabinoid with distinct receptor behavior from THC and is being studied for metabolic and appetite-related pathways.
Delta-8 THC
Delta-8 THC is a psychoactive cannabinoid often derived from hemp inputs, with active legal and safety debates.
Delta-9 THC
Delta-9 THC is the most recognized intoxicating cannabinoid and a central reference point in cannabis law.
Cannabis Science
The Endocannabinoid System
The endocannabinoid system is a signaling network involved in mood, pain, appetite, and homeostasis, and it is central to cannabinoid research.
Terpenes
Terpenes are aromatic compounds in cannabis and other plants that may influence sensory experience and potentially interact with cannabinoid effects.
Entourage Effect
The entourage effect is the theory that cannabinoids and terpenes may produce combined effects different from isolated compounds.
Cannabis Pharmacology
Cannabis pharmacology studies how cannabinoids are absorbed, distributed, metabolized, and produce effects in the body.
Bioavailability
Bioavailability describes how much of a cannabinoid dose reaches systemic circulation and can vary widely by product type.
Inhalation vs Edible Consumption
Inhaled products usually act faster and wear off sooner, while edibles typically start slower and can last longer with delayed peak effects.
Cannabinoid Metabolism
Cannabinoid metabolism describes how the body transforms cannabinoids into active and inactive metabolites over time.
Policy and Regulation
What Is Schedule I?
Schedule I is a federal controlled-substances category with strict restrictions that has historically included cannabis.
What Is Schedule III?
Schedule III is a less restrictive federal category than Schedule I and is central to current cannabis rescheduling discussions.
What Is Rescheduling?
Rescheduling changes where a substance sits within federal scheduling categories, which can alter compliance and economic conditions.
What Is Descheduling?
Descheduling removes a substance from federal controlled-substances schedules entirely, a broader change than rescheduling.
What Is 280E?
Section 280E is a US tax rule that can prevent standard business deductions for federally prohibited trafficking activities, including many cannabis operators.
Cannabis Banking Restrictions
Cannabis banking restrictions stem from federal legal risk and compliance burdens that can limit access to traditional financial services.
Federal vs State Cannabis Law
Federal and state cannabis laws can conflict, creating a dual-compliance environment for consumers, operators, and investors.
Interstate Commerce and Cannabis
Interstate commerce in cannabis remains constrained by federal law, shaping fragmented state-by-state supply chains.
