Effect of marihuana on hearing
The Journal of Otolaryngology
|June 1, 1976
Summary
This study found that smoking marihuana did not significantly alter hearing function in individuals with normal hearing. Researchers concluded that marihuana does not worsen auditory function based on audiological tests.
Area of Science:
- Audiology
- Pharmacology
Background:
- Previous research suggested marihuana may enhance hearing.
- This study aimed to objectively evaluate marihuana's effects on auditory function.
Purpose of the Study:
- To investigate the impact of marihuana smoking on various aspects of hearing.
- To determine if marihuana consumption leads to significant changes in audiological test results.
Main Methods:
- 30 healthy subjects were randomly assigned to smoke either marihuana or placebo cigarettes.
- Standard audiological tests were performed before and after smoking, including pure tone thresholds, speech discrimination, and acoustic impedance measurements.
Main Results:
- No significant changes in auditory function were observed in either the marihuana or placebo group.
- The study could not confirm hearing improvement, only that marihuana did not impair hearing in this cohort.
Conclusions:
- Marihuana smoking did not demonstrate a significant effect on hearing in individuals with normal auditory function.
- Further research is needed to explore potential therapeutic applications or risks of marihuana on hearing in different populations.
