⚠️ Cannabis Pregnancy Lactation Safety Simulator

A Developing Brain, Unexposed

Placeholder lead: fetal neurodevelopment proceeds rapidly, unexposed baseline.

• 250k/min: Neuron formation rate (placeholder stat)
• Active early: Endocannabinoid system (placeholder stat)
• Week 12: Placenta forms by (placeholder stat)
• All trimesters: Critical window (placeholder stat)

Why baseline neurodevelopment matters

Placeholder: rapid neuron migration and synapse formation occur continuously.

The endocannabinoid system in utero

Placeholder: fetal CB1/CB2 receptors guide normal circuit wiring.

THC Crosses the Placental Barrier

Placeholder lead: THC is lipophilic and passes the placenta readily.

• ~40–70%: Placental transfer (placeholder stat)
• ~1:3: Fetal:maternal ratio (placeholder stat)
• Days–weeks: THC half-life (placeholder stat)
• Smoked/edible: Route matters (placeholder stat)

Lipophilic transfer across the placenta

Placeholder: fat-soluble THC diffuses across placental membranes easily.

Frequency and dose effects

Placeholder: regular use raises fetal circulating THC levels more.

Potential Effects on Neurodevelopment

Placeholder lead: research links exposure to birth weight, cognition signals.

• Lower avg: Birth weight association (placeholder stat)
• Mixed evidence: Attention/behavior studies (placeholder stat)
• Some studies: Preterm birth signal (placeholder stat)
• Still evolving: Research status (placeholder stat)

Associations reported in cohort studies

Placeholder: lower birth weight and possible cognitive-behavioral links.

Confounding and research limitations

Placeholder: co-exposures and reporting bias complicate causal claims.

THC Concentrates in Breast Milk

Placeholder lead: fat-soluble THC pools in milk fat, above plasma level.

• ~4–8×: Milk:plasma ratio (placeholder stat)
• Weeks: Detectable duration (placeholder stat)
• Slower clearance: Infant metabolism (placeholder stat)
• Higher fat = more THC: Fat content link (placeholder stat)

Fat-soluble accumulation in milk

Placeholder: THC partitions into milk fat, concentrating over plasma.

Continued infant exposure risk

Placeholder: nursing infants keep absorbing THC with continued use.

Professional Guidance: Avoid Use

Placeholder lead: ACOG and AAP recommend avoiding cannabis throughout.

• Avoid use: ACOG guidance (placeholder stat)
• Avoid use: AAP guidance (placeholder stat)
• None established: Safe threshold known (placeholder stat)
• Recommended: Clinician counseling (placeholder stat)

Why major bodies advise abstinence

Placeholder: limited reassuring data plus plausible neurodevelopmental risk.

Placeholder highlight: no safe exposure level has been established.

Talking with patients about use

Placeholder: open, nonjudgmental counseling supports cessation and safety.
