It might also be the drugs. Moroccans are very moralistic about drinking. Islam forbids them to drink so they can't claim a drunken nightlife scene. They do drink, they just hide it, don't flaunt it and do it discreetly.
So the option is drugs which doesn't really have any religious rules.
I've been too Morocco a couple of times and wanted to go to Essaouira but every time we tried there was always a drugged out culture that we saw to the people that wanted to go there.
It's also famous for the Rolling Stones going there, smoking their brains out and finding their inspiration for their album 'Sympathy For The Devil' .... that particular song has an intro of them chanting "woo woo .... woo woo .... woo woo" ... and many people have suggested that is the sound of the pigeons they heard there that are everywhere in Morocco.
