Medicines based on cannabis can cause paranoia and anxiety in some people, according to a new study. As the BBC http://www.bbc.co.uk reports, Swiss researchers found that two out of eight men given drugs containing THC, a chemical extracted from cannabis, developed psychotic effects. According to the team of researchers from the University of Lausanne http://www.unil.ch , the public needs to be aware that cannabis medicine could have side effects. At present, the possibility of using THC to treat multiple sclerosis and pain relief is being explored.
