Drugs are everywhere, everyone uses drugs every day. Some people drink coffee with caffeine, people may use headache pills or other medication.
Alcohol is not viewed as a drug by western society because most people agree that alcohol is better than cannabis and other illegal substances.
The reason for this is because most people in western society link the use of alcohol to parties, celebrations, and having a good time.
The fact of the matter is that alcohol is the most deadly drug in the world. Alcohol carries a lot of short-term, and long-term health effects that people seem to ignore when drinking.
