I can start with my own observation.
Khat
Although this drug was presented to Somalis the beggining of 1900, it still can be inclusive into Somali culture because of the status of the "khat" in Somalia today.
Now this is one aspect of Somali culture that is not compatible with a free and healthy society whom is gonna be sustainable in Somalia.Khat consumption induces mild euphoria and excitement. Individuals become very talkative under the influence of the drug.
Those who abuse the drug generally cannot stay without it for more than 4–5 days without feeling tired and having difficulty concentrating. Some researchers also say that khat is “an amphetamine-like substance”, and those who use it are more likely to develop mental illnesses.
Withdrawal symptoms that may follow occasional use include mild depression and irritability. Withdrawal symptoms that may follow prolonged khat use include lethargy, mild depression, nightmares, and slight tremor. Khat is an effective anorectic (causes loss of appetite).
