Dabbing produced higher THC blood levels and stronger intoxication than other methods, but effects faded faster
Among 252 legal cannabis users, dabbing produced the highest plasma THC and strongest subjective effects compared to vaping, bongs, and joints, but intoxication from dabbing and vaping dropped off more quickly.
Quick Facts
What This Study Found
Dabbing was associated with higher plasma THC concentrations and subjective effects than flower-based methods (bong, joint); dabbing and vaping showed more rapid reductions in subjective intoxication over time.
Key Numbers
252 participants; 46.4% female; four administration modes compared; dabbing produced highest plasma THC and subjective effects; dabbing and vaping showed faster decline in subjective intoxication.
How They Did This
Secondary analysis of two quasi-experimental studies; 252 participants (46.4% female) self-administered legal market cannabis products via their preferred mode (dabbing, vaping, bong-like, joint-like); plasma THC and subjective effects measured.
Why This Research Matters
As dabbing and vaping gain popularity, understanding that these methods produce higher peak THC exposure but shorter subjective duration has implications for dosing, impairment assessment, and use patterns.
The Bigger Picture
The cannabis landscape has shifted from flower-dominant to diverse high-potency products, and research needs to account for how different administration methods fundamentally change the THC exposure profile.
What This Study Doesn't Tell Us
Naturalistic design means products varied in potency; no random assignment to modes; participants used their preferred mode (selection bias); could not control for tolerance differences; secondary analysis.
Questions This Raises
- ?Does the faster decline in dabbing/vaping intoxication lead to more frequent re-dosing?
- ?How should impairment testing account for mode-specific THC kinetics?

What do these levels mean? →Frequently Asked Questions
Which method of using cannabis produces the strongest effects?
Dabbing produced the highest plasma THC levels and strongest subjective intoxication compared to vaping, bong-like, and joint-like methods.
Do effects last as long with different methods?
No. Dabbing and vaping showed more rapid reductions in subjective intoxication over time compared to flower-based methods like bongs and joints.
