Even if you are not chemist, you may remember there are some types of alcohol. We drink ethanol though we can die by methanol. Methanol is not very difficult to get and that might cheaper than drinking alcohol. I remember beer in India was really cheap for us, though expensive enough for them who live in India. They are trying to find the cheapest alcohol though they needed to give their life. This is not only alcohol issue. Too cheap materials can include some safe issue. We still remember cheap raw meets killed a lot of people in 2011. We may need to pay attention for safe food and should not try the cheapest.
