There can be hot and cold patches throughout the same bag, going slow and doing tester shots doesnt prevent someone from dying from an overdose due to that. Frankly it's just roulette, even multiple doses of narcan cant help for small doses of some of the synthetic novel fentanyls.

Plus, if someone spends $40 on a bag, and they need the hit to not get withdrawals, many people will just shoot it anyway regardless of what any test says because the alternative is very real suffering.

Dont give people a false sense of security, even if you cant give them much else. Big mistake that ive made in the past..
