I dont know of any people who are happier addicted to hard drugs than not addicted to hard drugs. If the supply of hard & tainted drugs increases, then people with addictions are more likely to increase their consumption of these drugs.

The problem & solution space involves more than just enforcement. A root cause is the ineffectiveness & corruption in social safety net programs including housing, drug treatment, & other domains. Not saying we should not have any programs but the ineffectiveness with increasing budgets speaks for itself. Effective & efficient programs should be rewarded while ineffective & inefficient programs should be discontinued.

Government agencies which engage in harmful activities such as drug trafficking should be reformed or disbanded. I don't expect the status quo to change, as we didn't get into this mess with rational leadership, but its worthwhile to have a sober view of root causes to at least put pressure on leadership to be more rational.
