There is a correlation between illegal drug dealers and pressure on drug war funding; there is the cost of incarcerating those convicted of drug-related crimes; the cost of court costs; legal costs; the funding of police officers who fight the black market in drugs. Legalizing cannabis in Australia opens up many opportunities, for example legalizing the production and sale of cannabis will eliminate the black market and generate taxes for the government (Walters, 1993). Also based on the 2001 statistics on the decriminalization of drugs in Portugal, there has been an increase in the diffusion of treatment and a reduction in drug-related deaths (Hughes & Stevens, 2007). Legalizing cannabis could save $3 to $10 billion, and the focus could be shifted from interdiction, law enforcement, courts, and prison costs (Dennis & White, 1999). Now the emphasis has been shifted to drug addiction treatment and the increase in treatment has increased after legalization (Loo, et al., 2002). The decriminalization of drug possession has allowed drug users to seek early involvement of medical professionals and allow for more effective methods of intervention into drug problems (Hughes & Stevens, 2007). This has eliminated the stigma behind the drug and professionals are able to spot problem drug users. Furthermore, with decriminalization we have a more visible view of the number of active drug users. Robson (1999, p. 22) claims that “the vast majority of people who use drugs never come to the attention of doctors, lawyers or policemen”. Research is now more efficient, especially among the many who take an interest in understanding drug-related issues. Furthermore, more people now report drug use, so statistics are more accurate and measuring the rate of overall drug use is easier.
