How about a fruit ban?
If we accept the premise that most plants, in their raw state, are our natural foods and medicines, then no plant should be banned.
If we consider that some plants have the potential to be harmful to our health once processed, then are we considering banning all plants?
On that premise, should we be banning hops, because as a herb it is beneficial to our health, but processed into beer has the potential to cause health problems such as obesity, liver damage and violent behaviour?
Likewise with barley (whisky), sugar (rum), grapes (wine), plums (wine).
