There is no one answer to that question. Christianity encompasses a broad spectrum of views on drugs and alcohol.

'Christianity and alcohol'

Well Jesus turned water into wine for a party and at the last supper offered a cup of wine to his disciples. Thus Christianity has no problem with the moderate, social use of alcohol. This said, there are some Christian sects that have come to regard use of alcohol as evil (on the basis of what it can do if abused) and encourage their members to be "tea total".

Wine is considered a ritual drink in Christianity as it is a reflection of the blood sacrifice of the Christ. Since there is no blood sacrifice in Islam and alcohol is forbidden, wine has no role in Islam.

No drugs legal or illegal no alcohol and no smoking.

That just means that he is Straight Edge. It's not his actual religion.
