Natural (Non-Synthetic) Opioids

Some examples of natural opioids (non-synthetic) include:

1. Morphine: This is a naturally occurring opioid alkaloid that is extracted from the opium poppy plant. Morphine is a potent pain reliever that is commonly used in medical settings.
   
2. Codeine: This is also a naturally occurring alkaloid found in the opium poppy plant. It is often used as a cough suppressant and mild pain reliever.
   
3. Thebaine: This is another naturally occurring opioid alkaloid found in the opium poppy plant. While it has some analgesic properties, it is primarily used to synthesize other types such as oxycodone and hydrocodone.
   
4. Heroin: While heroin is a semi-synthetic opioid, it is derived from morphine which is a natural opioid. Heroin is a powerful and illegal drug that is highly addictive and has a high risk of overdose.

It’s worth noting that while these type are derived from natural sources, they can still be dangerous and have a potential for misuse. They should only be used under the supervision of a healthcare professional.
