| Codeine | Info |
|---|
| Summary | Codeine is a weaker opioid used to treat mild to moderate pain and to relieve cough. In many countries it is available over the counter in combination with paracetamol, which can easily be extracted to retrieve near-pure codeine. For this reason, it is used widely as a recreational opioid. It is metabolised into morphine in the body at a rate of 5% mg for mg. |
| Dose | Oral Light: 50-100mg Common: 100-150mg Heavy: 150-200mg NOTE: The ceiling effect differs from person to person, but it seems to fall between 400-600mg |
| Onset | 30-45 minutes |
| Duration | 3-6 hours |
| Avoid | People seeking codeine experiences from medications that contain acetaminophen (paracetamol) may be putting themselves at risk for acetaminophen-related complications such as liver damage. |
