“There is a substantial growth in the use of medical cannabis in recent years and with the aging of the population, medical cannabis is increasingly used by the elderly.
We aimed to assess the characteristics of elderly people using medical cannabis and to evaluate the safety and efficacy of the treatment.
Our study finds that the therapeutic use of cannabis is safe and efficacious in the elderly population. Cannabis use may decrease the use of other prescription medicines, including opioids.”
