It's like Coca leaves,
They tried to ban them before in their native country peru, it didn't work at all. They've been chewing coca leaves for god knows how long according to wikipedia thousands of years 8000+....
I don't see it the relevance of trying to ban certain things sometimes.
You want to ban something ban smoking please. Pointless. At least khat gives you a boost/has a purpose.
It's funny how we as a society decide to label certain things as ok and others as ghastly and dangerous!!1 and people eat it up because they are unable to self educate. I told someone once I tried a drug I won't say which but put it this way I researched it and gave it a whirl, they lost their **** going how it'll fry my brain. I said how many studies have you read about it? how much info do you actually know? you can guess they knew absolutely nothing.
I remember once someone told me drugs are terrible, I told them alcohol was a drug (I don't drink either only like maybe 3-4x a year). They looked at me perplexed and said yeah but it's legal..
Amazing.
