Flakka Cannibals

In 2030, Germany will be flooded with one of the world's most dangerous drugs, known as Flakka or Flex.
Drug addicts attack uninvolved citizens. Innocent children are killed by Flakka cannibals. People are jumped on and addicts bite their faces. Citizens no longer dare to go outside and live in fear of the Flakka cannibals.
The drug scene is getting out of control nation-wide.
Is it enough to lock up the drug addicts to get the state of emergency in Germany under control again?
Is a new law necessary that prohibits the use of drugs?
