Walt Disney World for Smokers
For guests who smoke tobacco, it is allowed on property, however, Disney has very strict rules. The parks are smoke-free and only have smoking sections at the front entrance, not inside.
All resorts are strict as well and have designated smoking areas outside of the hotels and restaurants.
To find the specific areas they are on the Disney Maps on the main website and on the My Disney Experience App.
Smoking of any other substance other than Tobacco is not allowed on any Disney Property.
