Marijuana has been associated with helping users sleep better. However, a recent study in the Journal of Addictive Diseases found the drug may be related to a user’s sleep troubles.
Daily pot smokers actually scored higher on the Insomnia Severity Index and on sleep-disturbance measures than those who used the drug less frequently. For example, 20 percent of the nonsmokers met the criteria for clinical insomnia, compared with 39 percent of the daily users meeting those criteria.
State laws regarding marijuana legalization may be changing, but so is our understanding of the substance’s health risks. Future research will investigate whether its benefits outweigh those risks.
