[Physiological dangers of the use of Cannabis sativa]

The increasing use of Cannabis sativa (dagga) raises the question whether it could cause physical harm to the user. The earlier belief that cannabis could be used effectively in the treatment of various illnesses contributes to the tendency of cannabis users to reject the possibility that it may be harmful to their health. Scientific research, however, indicates that cannabis has no medicinal value. On the contrary, it may cause serious physical damage.
