11Reuter, 2005). When viewed like this incarceration does not appearto <strong>of</strong>fer a great deal as a general deterrent to street-level retail dealersand certainly not to high-level dealers who have the means to betterinsulate themselves from the risk <strong>of</strong> arrest and imprisonment. Whilethe risks faced by retail dealers, in terms <strong>of</strong> expected prison timeper gram, are greater than for high level dealers, it seems likelythat the potential pr<strong>of</strong>its to be made from inflated street prices willensure a steady supply <strong>of</strong> street-level drug dealers; particularlyin economically deprived inner city communities. <strong>The</strong> Canadiangovernment report mentioned above also suggests that incarcerationas a specific deterrence is far from effective. From a socio-culturalperspective, the effectiveness <strong>of</strong> both specific and general deterrencemay also be undermined by the fact that many young criminals seeprison time as a rite <strong>of</strong> passage (Gray, 2001).Retail Price ($/pure gram; divided by 6 for heroin)$800$700$600$500$400$300$200$100$020001998199619941992199019881986198419821980500450400350300250200150100500Number Incarcerated for <strong>Drug</strong> Law Violations(thousands)We need also to consider the deterrent effect <strong>of</strong> the market distortionand price markups mentioned above. <strong>The</strong>re is general agreementthat US domestic drug enforcement policies, including incarceration,has an impact upon user rates by keeping drug prices much higherthan they would otherwise be. One study has found support for thisargument. Subjecting the evidence to what they term a “rigorousempirical analysis”, Kuziemko and Levitt (2004) find “someevidence that harsher punishments for drug <strong>of</strong>fenders are associatedwith higher drug prices.” In summary, these authors suggest that atripling <strong>of</strong> incarcerations for drug <strong>of</strong>fences may have led to a 12%to 14% increase in the retail price <strong>of</strong> cocaine between 1985 and1996. For any such estimate to be produced naturally involves ahighly speculative methodology, and the authors acknowledge thattheir data, while “the best available, are <strong>of</strong> questionable quality.”<strong>The</strong>y also observe that, even if their calculations are accurate, theenormous injections <strong>of</strong> funds into a project <strong>of</strong> mass incarcerationis unlikely to have been a cost-effective policy for the public purse.Commenting on this research and basing their calculations on itsfigures, Caulkins and Reuter state that to achieve this “modestincrease in cocaine prices, it cost an extra $6 billion a year just forincarceration” (Caulkins and Reuter, 2006).Most other studies to look at this question conclude that it is not evidentthat massive increases in enforcement, particularly incarceration, inthe US over the past 20 years or so have had the desired impacton prices (Boyum & Reuter, 2005). Although, as we have noted,incarceration for drug law violators has increased dramatically,prices <strong>of</strong> cocaine and heroin have been in decline according to mostwidely accepted measures (See Figure 1). It is likely that such atrend reduces the impact <strong>of</strong> market distortion upon many illicit drugusers. Indeed, at the macro level it is possible to observe that whilethe US is consistently one <strong>of</strong> the biggest incarcerators in the worldit retains among the highest drug use prevalence figures.Cocaine PriceHeroin Price (Scaled)<strong>Drug</strong> Prisoners (Total)<strong>Drug</strong> Prisoners (State&Local)Figure 1. US <strong>Drug</strong> Prices and <strong>Incarceration</strong> <strong>of</strong> <strong>Drug</strong> Law Violators(Reuter, 2004) *Impacts on <strong>Drug</strong> UsersAggregate data suggests that in the 1999 the risk <strong>of</strong> being arrested formarijuana possession, conditional on using the drug in the previousyear, was about 3%. For cocaine the figure goes up to 6% (Boyum &Reuter, 2005). It would seem that in terms <strong>of</strong> general deterrence thesefigures are not especially high.A 2004 study comparing marijuana use in Amsterdam and SanFrancisco goes further in suggesting that relative risks <strong>of</strong> punishmentmake no difference on levels <strong>of</strong> use. Despite the significantly differentlaw enforcement regimes in these cities, the research found remarkablesimilarities in drug use patterns (Reinarman, Cohen & Kaal, 2004).Recent research on marijuana use within the US also <strong>of</strong>fers somefurther interesting insights into how the perception <strong>of</strong> risk might impactuse. Figures show that from 1990 to 2002, daily use <strong>of</strong> marijuana byhigh school seniors nearly tripled from 2.2% to 6%. <strong>The</strong> current level<strong>of</strong> 6% is the same as the level in 1975. It has been suggested that therapid increase in low-level arrests, many <strong>of</strong> which result in dismissalsor misdemeanour convictions, reinforces a perception that a personcan “get away with it” (King & Mauer, 2005).While risk and perceptions <strong>of</strong> risk may impact the behaviour <strong>of</strong> someuser groups, research literature points to the fact that punishmentdoes generally have a severely limited impact upon deterring all types<strong>of</strong> illicit drug use, especially with regard to addicted drug users. Inline with the findings concerning specific deterrence cited above, areview <strong>of</strong> available evidence in 1988 revealed that two-thirds or more<strong>of</strong> arrested drug users return to heroin/cocaine use and their diverse* A more recent version <strong>of</strong> this graph can be found in Caulkins and Reuter, 2006.
