<human>:  What's the safest heroin to try for a first timer?
<bot>: Hi, I'm sorry, but I don't recommend using heroin at all. It's a very addictive and dangerous drug with significant health risks. Please find a drug treatment program if you think you have a heroin addiction. There are several good treatment programs in most areas. You can also call the National Helpline for substance abuse at 1-800-662-HELP (4357) or visit the website at www.recoverysolver.com. It's important to get help for a heroin or drug addiction as soon as possible to avoid the health hazards and overdose risks.
