Dose Tier Summaries
Minimal perceptible opioid effects at this range. A faint sense of warmth and mild anxiolysis may emerge as CYP2D6 begins converting ethylmorphine to morphine, though the subjective shift is subtle and may be imperceptible in CYP2D6 poor metabolizers. Physically, slight muscle relaxation and a gentle easing of bodily tension are the most noticeable signs. No significant sedation, analgesia, or respiratory effects are expected. This range falls below the established therapeutic antitussive dose. CYP2D6 phenotype is the dominant variable at this level — an ultrarapid metabolizer may perceive mild opioid effects where a poor metabolizer notices nothing.
Work-notes specify threshold at ~20 mg. No controlled subjective-effects studies exist for ethylmorphine at any dose. Description inferred from mu-opioid agonist class pharmacology (morphine/codeine) and the prodrug conversion kinetics described in Aasmundstad 1995 and Hedenmalm 1997.

Evidence basis: structural_analogy
Mild analgesia and anxiolysis become clearly perceptible. A gentle sedation settles in alongside bodily warmth and slight heaviness. Antitussive effects are present at this range, which overlaps with the lower end of therapeutic dosing. Physical effects include mild muscle relaxation, possible pupil constriction, and a subtle reduction in pain sensitivity. Nausea is uncommon but possible in opioid-naive individuals. Cognitive function remains largely intact, though slight thought deceleration may be noticed. Comparable in character to a low therapeutic dose of codeine, though ethylmorphine produces proportionally more morphine per milligram (7.0% vs 3.8%).
Work-notes specify light at 40–50 mg. Therapeutic range per Wikidoc is 5–50 mg, placing the light tier at the upper end of therapeutic dosing. Effects inferred from morphine/codeine class and the comparative PK data (Hedenmalm 1997).

Evidence basis: structural_analogy
Clear mu-opioid agonist effects emerge — moderate analgesia, noticeable sedation, and a warm euphoric contentment. Anxiety suppression is pronounced. Pupil constriction is visible and consistent. The antitussive ceiling is reached within this range. Bodily heaviness and muscle relaxation are prominent. Nausea is possible, particularly in opioid-naive users. Constipation onset begins. Mild respiratory slowing occurs but is typically not subjectively distressing at this level. A body high characterized by diffuse warmth and spontaneous pleasant sensations is common. Cognitive effects include thought deceleration, focus suppression, and mild motor control impairment. This range straddles the upper therapeutic boundary — doses above 50 mg exceed published therapeutic recommendations.
Work-notes specify common at 50–100 mg. Published therapeutic range tops out at 50 mg (Wikidoc), so the upper half of this tier is supratherapeutic. Effect descriptions inferred from mu-opioid class pharmacology. The discrepancy between therapeutic and seed 'common' dose is noted per work-notes instruction.

Evidence basis: structural_analogy
Pronounced sedation and euphoria dominate the experience. Analgesia is substantial. Cognitive impairment becomes significant — decision-making, psychomotor coordination, and attention are markedly reduced. Emotional suppression and a sense of detached contentment are characteristic. Respiratory depression risk becomes clinically significant at this range. Nausea and vomiting are likely in non-tolerant individuals. Constipation is expected. Pupil constriction is marked. Sexual arousal suppression is typical. The body high is intense, with heavy sedation that may approach somnolence at the upper end. This range exceeds all published therapeutic dosing. Driving and machinery operation are absolutely unsafe. The risk of adverse outcomes increases substantially, particularly in CYP2D6 ultrarapid metabolizers who may experience morphine levels equivalent to a heavy dose.
Work-notes specify strong at 100–200 mg, well above the 5–50 mg therapeutic range. All effect descriptions are class-inferred from morphine/codeine pharmacology. Respiratory depression risk escalation at supratherapeutic doses is a well-established mu-opioid class property.

Evidence basis: structural_analogy
This range carries severe risk of life-threatening respiratory depression. Sedation is profound and may approach or reach unconsciousness. The one published fatal ethylmorphine overdose (Kintz et al. 1994) occurred at blood concentrations consistent with doses in this range. Nausea, vomiting, and aspiration risk are high. Cardiovascular depression may occur. Complete psychomotor incapacitation is expected. The combination of respiratory depression and loss of consciousness creates extreme overdose danger, compounded by the unpredictable CYP2D6-dependent morphine formation rate. Co-ingestion of any CNS depressant at this dose level is potentially fatal. Naloxone should be immediately accessible. This range is never therapeutically indicated and represents a medical emergency threshold.
Work-notes specify heavy at 200+ mg. Fatal case (Kintz 1994) at 488 ng/mL blood (~9x therapeutic level) provides the only direct human toxicity anchor. All other characterization is class-inferred from morphine overdose pharmacology. Approximate lethal dose of ~500 mg from Wikidoc is unverified (flagged as safety-citation-needed).
