Qian ZJ, et al. - In this cross-sectional analysis of nationally representative data, researchers intended to determine if there was a connection between marijuana use and the prevalence, severity, and rate of occurrence of tinnitus. Statistical analysis was carried out on data collected from 2,705 non-institutionalized adults (aged 20 to 69) who had audiometric screening and questionnaires on hearing, drug use, current health status and medical history were administered. Findings revealed that marijuana use at least once per month for the previous 12 months was significantly linked to experiencing tinnitus during that 12-month month. Those using marijuana were more likely to experience tinnitus after adjusting for covariables including age, gender, audiometric hearing loss, history of noise exposure, depression, anxiety, smoking, use of salicylate, cardiovascular disease, hypertension, and diabetes. An association was found between regular marijuana use and prevalent tinnitus. There was no dose-response, however, between the use of marijuana and tinnitus. The link between use of marijuana and tinnitus is complicated, and psychosocial factors are likely to modulate it. Use of other substances like alcohol, cocaine, methamphetamine, and heroin was not linked to tinnitus.
