Why do blacks suck their teeth?

During my studies on the uses of jenkem I have found that this is something that blacks do regularly. Is this a side effect of their consumption of this substance?

Marylin B, I like your initiative in finding out more about jenkem. Would you like to partake in my research and thus experience the substance at first hand? I may even have an opening for a laboratory assistant. Are you a blonde?

Out of curiosity, I had to look up "jenkem" and this is part of what I found: Jenkem is an inhaled gas which can result in dissociation and hallucinations. It is made from fermented sewage, is primarily composed of methane, and is popular amongst the street children of Zambia.

No one knows how or when the children first began manufacturing jenkem, but according to the BBC it has been around since at least 1997.

Its effects last for around an hour and consists of auditory and visual hallucinations. The raw materials are plentiful and freely available in the form of fecal matter from the open sewers of the major towns, e.g. Lusaka. This is then fermented in containers and the fumes are inhaled.

If this is what poor black children--and whites, too--have to do to escape their deplorable environment, then I feel bad for the human race. The image of them sucking on their teeth afterwards only makes it more deplorable.
