Tinnitus from Ginkgo Biloba

Tinnitus is the perception of sound in the absence of an external acoustic stimulus. The perceived sound is most commonly described as ringing, but can also manifest as buzzing, hissing, clicking, roaring, or pulsing. In the context of psychoactive substance use, tinnitus can arise from direct ototoxic effects of certain compounds, from substance-enhanced vulnerability to noise-induced hearing damage, or from neurological alterations in auditory processing.

The auditory system is a complex pathway from the cochlea (inner ear) through the auditory nerve, brainstem nuclei, thalamus, and auditory cortex. Tinnitus is thought to arise when damage to the peripheral auditory system (particularly the outer hair cells of the cochlea) reduces normal input, causing central auditory circuits to increase their gain in an attempt to compensate. This amplified neural activity in the absence of corresponding external sound is perceived as tinnitus.

Several substance-related mechanisms produce tinnitus. Ototoxic substances directly damage cochlear hair cells or the stria vascularis. Aspirin and other salicylates at high doses reversibly inhibit the motility of outer hair cells, producing dose-dependent tinnitus that typically resolves when the drug is discontinued. Aminoglycoside antibiotics cause irreversible hair cell death. Quinine produces reversible ototoxicity. Loop diuretics can cause temporary ototoxicity through effects on endolymph composition.

Stimulants pose an indirect but important risk: by increasing alertness, energy, and pain tolerance, they enable and encourage prolonged exposure to loud music at concerts, clubs, and festivals. The vasoconstriction caused by stimulants may also reduce cochlear blood flow, potentially making the inner ear more vulnerable to noise damage. MDMA users at music events face a particular convergence of risk factors -- loud music, prolonged exposure, reduced pain awareness, and potential ototoxic effects of the substance itself.

Cannabis and psychedelics can alter the subjective perception of existing tinnitus, sometimes making it more noticeable during the experience. Some users report temporary tinnitus during psychedelic experiences that resolves completely afterward, possibly reflecting altered auditory processing rather than true cochlear damage.

Prevention is paramount: wearing earplugs at loud events, limiting exposure duration, and avoiding the combination of ototoxic substances with loud environments. Once established, chronic tinnitus is difficult to treat, though cognitive behavioral therapy, sound therapy, and tinnitus retraining therapy can help manage the condition.
