Chewing miraa bad for mental health, Kemri scientists say

Chewing miraa, the report says, is significantly associated with strange experiences and hallucinations – two symptoms indicative of mental problems. In both instances, the scientists were citing data collected from 831 residents of Meru and Embu counties in 2015 in a study funded by the Government at Sh38 million. Of the 831 study participants, 306 or about 37 per cent were found to chew miraa, with more than half being men. About 14 per cent of children aged 10-17 were also found to chew miraa. This is described as worrisome because early initiation of substance use is linked to increased risk of drug-related diseases.

The study reports a link between chewing miraa and symptoms indicative of mental problems that were independent of alcohol and or tobacco. But last Thursday, Dr Evans Amukoye, deputy director of Kemri, told The Standard there was no contradiction in the two positions presented by the researchers. He said in both cases, an association of mental illness and use of khat was found but when controlled for alcohol and other drug use, the link was not significant.

In the initial presentation made at a scientific conference in Nairobi in 2017, lead investigator Prof Charles Mbakaya linked miraa to reduced appetite, low obesity and increased libido. “We could be condemning and ruining the reputation of a plant that has the potential of becoming a billion-dollar industry,” Prof Mbakaya, now with Rongo University, had said. In a project brief on the online platform Researchgate, Mbakaya says during data collection men and women reported better sexual performance among persons chewing khat. When last week in an email we asked Mbakaya about the contradictions, he said the raised issues are weighty and require time for an appropriate feedback.
