Good sleep is an elusive luxury. After a stressful day it can take forever to get to sleep. The severity of insomnia typically worsens as we age. Every year after puberty it becomes more difficult to fall asleep and stay asleep. Insomnia leaves us feeling dissatisfied with our sleep and facing the new day with fatigue, low energy, difficulty concentrating, generalized anxiety and decreased performance in work or at school. There are many causes for insomnia, including changes in our sleeping environment, shift work, clinical disorders such as depression or mania and most medications. Over-the-counter and prescriptions medications are common solutions for the complex causes of insomnia. A study in 147 participants with and without sleeping difficulties found that cannabis use reduced the time taken to get to sleep in both groups. A further 2014 study looked at the therapeutic effect of CBD in people whose sleep was disrupted by anxiety, such as in the case of post-traumatic stress disorder (PTSD).
The research team noted that, at the time, PTSD was an acceptable condition for medicinal cannabis use in five states, and cannabis use for medical reasons was growing in the U.S. The study concluded that many people with PTSD used cannabis to help them sleep.
