I can't tell if you're being serious or not, but I feel it needs to be clarified.
The reality is free drugs at safe injection sites, supported by the tax payer, is cheaper for the tax payer. Overdoses and emergency services for overdoses cost a LOT of money. "a period of 2 years and 3 months", "with a savings of over $2.3 million for the lifetime of the program"[0].
Roughly $1 MM per year for just the 1 city in this study (and the population of the city is relatively small).
Additionally, there is a reduction in overall costs funded by the tax payer of rehab, help programs, etc because of benefits from colocation with the safe injection sites.
Additionally, this study doesn't even include the long term savings from reduced police/boarder patrol workload. Not only do free drugs reduce the need for petty theft to fund an addiction (costing tax payer time to file insurance claims - let alone the improved safety of no more petty theft), but when drugs are free, there is no longer a profit for organized crime and smuggling. Reducing the overall tax payer burden for the city / country.
