For most people drinking is a normal practice that they may do at a party or some kind of celebration or night out. They don't have a problem with it.
There are those people who are trying to be friendly and have a laugh that may want to encourage others to have a drink (not 10 drinks) to break down social barriers, then there are a few like us who think people don't drink are weird and to stay say from.
If people have seen you drink before and suddenly you are not they will want to know why or encourage you to drink. That's completely normal if they know you. The only way to ensure they don't keep asking you to drink is to be honest, e.g. If you had pancreatitis and let them know that drink could kill you then you may hear a couple of jokes but no one is going to actively encourage you to drink.
