So Muslims are discouraged from incest, smoking, drug consumption, becoming a terrorist and drinking alcohol, but are not forbidden from doing any of the aforementioned.
I once took a cab at rush hour during Ramadan, and had a chat with the driver, a calmly late middle aged man. We talked about fasting, and its health benefits, but also its religious dimensions. When i was reaching my destination, i casually commented on the pack of smokes on his dash board. I asked him if he could smoke when he was fasting. He said no problem, after 7pm, he could drink, smoke, and have a cheap fuck on the go. Quite an education for me as a very young man.
