Cannabis is a plant-based drug. It can be smoked, eaten or vaped.
Cannabis is an illegal drug that is made from a group of plants; Cannabis sativa, Cannabis indica, and Cannabis ruderalis. Cannabis plants have psychoactive properties, and people use it for different reasons, such as to relieve mental or physical problems. However, although benefits may be felt initially, in the longer term it can make problems worse, or create new ones. Cannabis use is risky as it affects different people in different ways and no one can tell what their reaction may be.
Recent cannabis use has been shown to affect extremes of nightly sleep duration, being either less than six hours or more than nine hours, with more intense patterns among heavier users.
Almost a third of 17-year-olds have tried cannabis and one in 10 have tried harder drugs, such as cocaine, ecstasy and ketamine, with similar rates of experimentation regardless of parents’ education level, finds a new study by UCL Institute of Education (IOE) researchers.
