“Cannabis has been used for pain relief and to promote sleep for thousands of years. Over the past several decades in the United States (U.S.), a therapeutic role for cannabis in mainstream medicine has increasingly emerged. Medical cannabis patients consistently report using cannabis as a substitute for prescription medications. Both pain relief and sleep promotion are common reasons for cannabis use, and the majority of respondents who reported using cannabis for these reasons also reported decreasing or stopping their use of prescription or over-the-counter analgesics and sleep aids. While adult-use laws are frequently called “recreational,” implying that cannabis obtained through the adult use system is only for pleasure or experience-seeking, our findings suggest that many customers use cannabis for symptom relief.”
