Methanol poisoning is a possible occurrence from the ingestion of ‘chang’aa’, Kenya’s most common surrogate alcohol, and is caused by the conversion of methanol to toxic chemical formate.
A common solution to methanol poisoning is the ingestion of ethanol, which stops this conversion.
Ingestion of “normal” alcoholic beverages, which contain ethanol and no methanol, can therefore provide relief to those suffering methanol poisoning, one of the consequences of ingesting illicit alcoholic beverages such as ‘chang’aa’.
Similarly, the availability of affordable, well-regulated alcoholic beverages has the potential to be a solution to Kenya’s illicit brews problem.
The substitution effect is the change in demand for a product as a result of a change in the relative price of the good compared to that of a substitute good i.e. if a product becomes more expensive relative to a substitute, some consumers will consume less of the product and more of the substitute.
As taxes on alcohol increase, not all alcohol is affected equally. Licit alcoholic beverages increase in price as producers pass on increased taxes to consumers while illicit alcoholic beverages, which are not taxed, maintain their low prices.
This means the price of legal alcoholic drinks increases relative to that of illicit brews, leading to substitution by some consumers from consumption of the former to consumption of the latter.
According to Retail Trade Association of Kenya CEO Wambui Mbarire, “repeated tax increases on alcohol, for example, have created a situation whereby nearly half, about 44 percent of the alcohol consumed in Kenya is illicit.”

This substitution effect is also shown by Kenyans in border towns, who are willing to cross the border to buy alcoholic beverages which are more affordable in Uganda and Tanzania.
Moreover, there are reports of market dominance, in low-income estates such as Dandora and Mwiki, of cheap spirits that sell 250ml bottles of spirits for KES 120 against typical prices of KES 200 to KES 255 by evading taxes, providing competitive pricing.
As these untaxed spirits also count as illicit alcohol consumption due to the lack of regulation, they provide a clear example through which we can observe the economic theory behind this.
Sin tax detaches product price from economic reality, creating a profit margin that traffickers in the black market grab as it exceeds the risks and costs of getting caught.
By reducing the taxes on alcohol, legal and well-regulated alcoholic beverages can be priced competitively against illicit brews, reducing consumption of the latter by incentivizing low-income earners to avoid consuming them.
