From a business and investment standpoint, addiction rehab stocks are tricky because you don't want to offend anyone when covering the market potential of the targeted segment.

Let's face it: It's hard to translate data on alcoholism or opioid rates to monetary figures because it communicates that there's money to be made in the industry (i.e. from addicts). The opioid addiction market alone, for instance, is worth $23 billion, according to a Globe Newswire report.

Found below are addiction rehabilitation companies of different market capitalizations that are taking advantage of the size and revenue potential of the market in full force:
