Euphoria, ecstasy, uncontrolled giggling and sedation are commonly experienced by people inhaling imphepho smoke. Violent mood swings, mental confusion and personality changes have not been reported. Other symptoms may be more rare and are normally seen in connection to the African traditional beliefs, mild hallucinations (such as seeing everything bathed in a gentle golden light) are seen as 'visions' and "speaking in tongues" has been known. Whether these are a result of the effects of the plant or of the psychological state of those involved in the rituals is uncertain. There is no evidence that even prolonged heavy use of imphepho can lead to any sort of physical or psychological dependency and there is no evidence of any health problems arising from prolonged use (apart from those associated with smoke inhalation perhaps).
