The Malaysian state of Pahang - the biggest on peninsular Malaysia and the third biggest in Malaysia, banned discos. Seriously. Not for Islam, but for… drugs:

The police have singled out discotheques as places where youths consume ecstasy and dancing in drug induced stupor called “goyang kepala.”

Recently, the federal government banned poppy seeds (kas-kas) in the nations popular mamak (Indian Muslim) restaurants. Because, apparently, it is too addictive.
