According to the thread on /r/europe that person smoked weed and lied about it on their immigration form.

The tweets just saying “drug use” and then you hear it’s weed is ridiculous. Why wouldn’t they just state that they lied on their immigration form about drug use?
In other news, FB has been using whatsapp metadata to coordinate genocide campaigns in Gaza. What’d all those dead civilians (including infants) do, again?
Presumably they signed a TOS, so it’s OK.
