The Canadian military is issuing a malaria drug that can produce anxiety, paranoia and psychotic behaviour

When Canadian soldiers deploy on an upcoming peacekeeping mission in Africa, some of them may be taking an anti-Malaria drug called mefloquine. Soldiers who have taken it before say they experienced paranoia, hallucinations and psychotic behaviour. Health Canada says the effects can last for years. The US special forces has banned mefloquine. But the Canadian military continues to issue it, albeit far less often than it used to.
