Quote: "We have drug testing in sport and many other work places. Why don’t our mp’s face random drug tests, with their seat going to a by election for any that fail.'"
Drug use should be decriminalised, not further outlawed and greater punishable penalties being enforced for their use (and don’t mix up use with growing, dealing and trafficking - they should still be criminalised).
The more you restrict and outlaw drug use, the more underworld activity there is. More illegal money changing hands, more robberies, more kidnappings, more violence, more murders, more health complications and more of the dark world activity (human trafficking, child exploitation and abuse etc.) due to the underworld growing and darker areas growing within it with people/organisations becoming more secretive and getting away with more because these people/organisations activities are harder to detect.
Since Portugal decriminalised drug use in 2009 there have been far fewer robberies, kidnappings, murders, STIs, drug related diseases (infections through sharing needles, for example), overdoses and less underworld activity.
