Dabbing, a method of consuming highly concentrated marijuana, often leads to intense highs and extreme physiological effects like passing out and respiratory issues, according to Twitter data. Further research is needed on these health consequences.
Area of Science:
- Cannabis research
- Social media analysis
- Public health
Background:
- Dabbing involves inhaling vapor from heated, highly concentrated marijuana.
- Understanding the self-reported effects of dabbing is crucial due to its increasing popularity.
Purpose of the Study:
- To explore themes related to the consequences of dabbing marijuana concentrates.
- To analyze self-reported physical and psychological effects from dabbing.
Main Methods:
- Collected 206,854 dabbing-related tweets from January 2015.
- Coded a random sample of 5000 tweets for content using crowdsourcing.
- Analyzed full sample for respiratory effects and passing out using keywords.
Main Results:
- 71% of sampled tweets discussed dabbing marijuana concentrates.
- Common themes included intense highs (22%), excessive use (15%), and extreme physiological/psychological effects (37%/17%).
- Passing out (14%) and respiratory effects like coughing (9%) were significant, with users intending to pass out (45%).
Conclusions:
- This study provides insight into the self-reported effects of dabbing marijuana concentrates.
- Highlights the need for further research into the health consequences of concentrate use.

Drugs Acting on Autonomic Ganglia: Stimulants
Ganglionic stimulants activate NM nicotinic receptors in autonomic ganglia, falling into two categories: nicotine mimetics [e.g., lobeline, dimethylpiperazine, tetramethylammonium] and muscarinic receptor agonists [e.g., muscarine, methacholine]. The first category's action is rapid and blocked by nicotinic receptor antagonists, while the second category's action is delayed and blocked by atropine-like agents. Nicotine, an alkaloid, affects the heart rate by stimulating sympathetic or...
