What is the difference between rehab and rehabilitation?

"Rehab" is a colloquial term often used to refer to rehabilitation, particularly in contexts like substance abuse or physical therapy. Rehabilitation encompasses a broader scope, involving various therapeutic processes aimed at restoring function and improving quality of life after illness, injury, or addiction. While "rehab" typically implies a structured program, rehabilitation can include a wide range of services and support systems tailored to individual needs. Ultimately, both terms focus on recovery and improvement, but "rehab" is more specific and informal.
