They also don't think police should be notified about their children's drug use in every instance. Parents feel they should judge each case by its own circumstances.
The Salvation Army interviewed 11 parents and 23 youngsters, aged 16 to early 20s. All of those surveyed opposed the stop-and-search proposal and said they would not ask the police to help family members quit drugs.
A single mother, who sent her 22-year-old son to a drug rehabilitation centre, said: "It's useless to force someone with no motivation to quit drugs. [My son] left home for 14 days after leaving the institution and I thought I would never see him again."
Her son eventually quit drugs with support from his family.
The Salvation Army said the key to winning the drug war was busting the suppliers and giving more support to social workers. These people are able to use softer tactics to convince young drug users to kick the habit.
