Study Notes
Cannabis and its Effects
- Cannabis, its legal status, medicinal and recreational uses, and potential health hazards are discussed.
- Cannabis is categorized into strains: sativa, indica, ruderalis, and hybrids.
- THC (delta-9-tetrahydrocannabinol) is the primary psychoactive compound, causing the "high."
- CBD (cannabidiol) is used medicinally for pain management and anxiety but potential risks exist depending on the source and dosage.
- CBN (cannabinol) is present in some products and also considered psychoactive, but less studied compared to THC and CBD.
- Cannabis contains over 70 psychoactive compounds, many not fully understood.
- Strain differences and their various compounds (THC, CBD, CBN) affect the brain and body.
- Dosage, usage frequency, profession, genetics, sex, and age influence cannabis effects.
- The podcast explores the science behind cannabis's effects on the brain and body, including how its chemical compounds cause the "high."
Podcast Details
- The podcast is independent of the host's Stanford teaching and research.
- It provides free information about science and scientific tools.
- Offers a premium channel ($10/month or $100/year) for AMAs, premium content, and research support.
- Non-Sleep Deep Rest (NSDR) protocol is a free resource on YouTube.
- NSDR aids in deep relaxation, sleep recovery, dopamine restoration, and anxiety management.
Sponsorship Information
- Levels monitors blood glucose using continuous glucose monitors (CGM).
- Thesis provides custom nootropics for focus, energy, and clarity.
- InsideTracker analyzes blood and DNA data for personalized nutrition.
- Momentous Supplements offers supplements for sleep, focus, energy, and hormone regulation.
The Cannabis Plant and Its Components
- Cannabis has over 400 biologically active compounds, some psychoactive.
- Three primary cannabis strains are sativa, indica, and ruderalis.
- Ruderalis is rarely used recreationally or medicinally.
- Sativa and indica differ morphologically: sativa is taller with longer leaves, while indica is shorter and denser.
- Morphology influences the concentration of psychoactive compounds.
- Cannabis is consumed via smoking, edibles, transdermal patches, and sublingual applications.
- Heat-released psychoactive compounds are inhaled, absorbed into the bloodstream via the lungs.
- Psychoactive compounds can cross the blood-brain barrier, affecting brain function.
Effects of Sativa and Indica
Sativa Varieties
- Produce a "head high," resembling stimulant effects.
- Associated with invigoration, alertness, and heightened creativity (further research needed).
- May reduce pain perception.
- Often used for pain relief and management.
Indica Varieties
- Produce a full-body relaxation effect.
- More sedative than sativa, often used for sleep.
- Can help relieve anxiety.
- Commonly referred to as "in-da-couch" due to its sedative properties.
Hybrid Strains
- Hybrid strains are blends of sativa and indica genetics in varying ratios.
- Growers control sativa/indica ratios to create desired effects.
Cannabis Type Classification
- Cannabis is classified as Type 1, Type 2, or Type 3 based on the THC:CBD ratio.
- Type 1: High THC, low CBD, strong psychoactive effect.
- Type 2: Equal THC and CBD, balanced psychoactive effect.
- Type 3: High CBD, low THC, potentially therapeutic with minimal psychoactivity.
Cannabinoid Receptors and Endogenous Cannabinoids
- The body possesses cannabinoid receptors (CB1 and CB2).
- The receptors are also targeted by endogenous cannabinoids (AEA and 2-AG), naturally produced chemicals.
- Endogenous cannabinoids influence mood, perception, immune function, hunger, etc.
- THC and CBD bind more strongly to receptors than endogenous cannabinoids, causing stronger effects.
Analogy to Hormones
- Synthetic hormones, like testosterone, often have stronger effects than their natural counterparts.
- Similarly, THC and CBD can have stronger effects on cannabinoid receptors than endogenous cannabinoids, potentially causing supra-physiological effects on the body.
Endogenous Cannabinoids
- Endogenous cannabinoids, like anandamide (AEA) and arachidonoyl-glycerol (2-AG), exist throughout life.
- Released from post-synaptic neurons.
- They act retrogradely (backwards) to presynaptic neurons, decreasing neurotransmitter release.
- Involved in long-term potentiation and depression of neural connections.
- Influence mood, energy, creativity, relaxation, short-term memory.
Cannabinoid Receptors
- Two main cannabinoid receptors: CB1 and CB2.
- CB1 receptors are predominantly found in the nervous system, including the brain (prefrontal cortex).
- CB2 receptors are primarily found in bodily tissues, including the immune system, liver, and other organs.
Effects of Cannabis
- Cannabis (including THC and CBD) strongly binds to CB1 receptors, surpassing endogenous cannabinoids.
- Effects are usually stronger and more prolonged than with endogenous cannabinoids alone.
- High potency and binding strength can cause dysregulation of the endogenous cannabinoid system, potentially causing problems.
Cannabis in the Body
- Cannabis quickly enters the bloodstream, reaching the brain within 30 seconds.
- Peak concentrations and effects occur between 30 and 60 minutes.
- Effects typically last 3-4 hours, varying with individual metabolism and usage frequency.
- THC and CBD are highly lipophilic (fat-soluble), easily entering fatty tissues, and remaining there for extended periods (up to 80 days).
- Fat loss does not eliminate THC and CBD, as these are stored in various fatty tissues.
Effects of Cannabis Varieties
- Sativa varieties are associated with elevated mood, alertness, talkativeness, increased focus, and "head high."
- Indica varieties tend to have sedative effects, relaxation, and "body high."
- Effects stem from CB1 receptor activation in diverse brain regions and circuits, impacting mood, cognition, and behavior.
THC and CBD Effects
- THC and CBD bind to CB1 receptors, affecting neuron activity.
- Effects vary depending on the specific brain region (e.g., different effects in the prefrontal cortex vs. amygdala).
Sativa vs. Indica
- Sativa varieties generally increase prefrontal cortex activity, leading to focus enhancements.
- Indica varieties often decrease prefrontal cortex activity, promoting relaxation.
- Both types can suppress activity in the basal ganglia and cerebellum, potentially affecting coordination.
Cannabis and Anxiety
- Anxiety and paranoia can be experienced by some cannabis users, regardless of strain or THC/CBD ratio.
- No reliable predictors for who will experience anxiety vs. relaxation.
- Increased cannabis consumption may not reduce, but potentially exacerbate, anxiety.
Cannabis and Memory
- Cannabis, particularly indica strains, can affect short-term memory due to hippocampus activity reduction.
- Long-term cannabis use can also impact long-term memory.
Cannabis and Appetite
- Cannabis often increases appetite ("the munchies") due to CB1 receptor abundance in the hypothalamus.
- THC and CBD activate hypothalamic neurons, amplifying appetite.
- Cannabis can have a cognitive component, leading to increased food cravings.
- THC and CBD can also influence blood sugar.
Cannabis and Pain
- THC and CBD might offer pain relief due to CB1 receptors in the spinal cord.
- THC potentially provides more pain relief than CBD.
- Pain relief perception is often subjective and affected by individual focus.
Cannabis and Creativity
- Cannabis is often associated with enhanced creativity.
- Creativity is linked to convergent and divergent thinking.
- Research suggests that some strains and doses might improve both convergent and divergent thinking, potentially fostering creativity.
Cannabis Use and Science
- Majority of cannabis research focuses on THC's effects, not adequately distinguishing sativa/indica varieties.
- Cannabis science is struggling to keep pace with the recreational market's experimentation with different strains and methods.
- Cannabis's effects are highly variable, dependent on the individual and context.
Why People Use Cannabis
- People use cannabis for various reasons, including pain relief, relaxation, anxiety reduction, and fostering creativity or altered states of consciousness.
- Many seek cannabis to induce desired mental states, including creativity.
