Implication

Experimental analysis reveals inhaled heroin provides enhanced analgesic effects compared to subcutaneous injection, indicating its unique pharmacological properties.

Key Points

Inhaled heroin demonstrated significantly stronger analgesic effects than subcutaneous injection.
Both inhalation systems maintained stable drug delivery with linear relationships between dose and blood concentration.
The study used liquid chromatography–tandem mass spectrometry to evaluate heroin and metabolite levels in blood.
Findings emphasize the acute brain access via the olfactory pathway that enhances the potency of inhaled heroin.
