Weed solves heroin. Nope, this isn’t some weird new rock-paper-scissors game. Marijuana really does appear to help the growing heroin problem.
It turns out that cities which have adopted medical marijuana have seen a drop in opiate overdoses and addiction treatment admissions. Why? Because the marijuana is being used in place of prescription painkillers. Those pills are dangerous enough, but worse they can be a gateway to heroin addiction. If people get fewer prescriptions for opiate drugs, you have fewer problems down the road.
Is there nothing marijuana can’t do?
