Ok the math isn’t perfect here because many addicts are in multiple categories, but I think it’s interesting that there are 24 addiction categories that have been shown on Intervention but alcoholism is represented in 28% of the episodes.

Also interesting:

• Only 2 people have been addicted to cocaine (not crack) by itself. 85% of the cocaine category are people who were addicted to something else as well, most frequently heroin.
• No one was addicted to Benzos (i.e. Xanax) only. Every Benzo addict was also addicted to at least one other drug.
